Materials science is the scientific discipline responsible for investigating the relationship between the structure and properties of materials. At the same time, it is worth clarifying that materials engineering is based on this, the properties-structure-processing-functioning relationships, and designs or projects some possible structure of the material, to achieve a predetermined set of properties.
Materials science is, therefore, a multidisciplinary field that studies fundamental knowledge about the macroscopic physical properties of materials and applies them in various areas of science and engineering, ensuring that they can be used in various works, machines and tools, or converted into products necessary or required by society. It includes elements of chemistry and physics, as well as chemical, mechanical, civil, electrical, medical, industrial, biological and environmental science engineering. With media attention focused on nanoscience and nanotechnology in recent years, materials science has been promoted in many universities.
Despite the spectacular progress in knowledge and development of materials in recent years, the permanent technological challenge requires increasingly sophisticated and specialized materials.
History
Historically, the development and evolution of societies have been closely linked to the ability of their members to produce and shape the materials necessary to satisfy their needs. Prehistorians have found it useful to classify early civilizations based on some of the materials used: Stone Age, Copper Age, Bronze Age or Iron Age. This last sequence seems universal in all areas, since the use of iron requires a more complex technology than that associated with the production of bronze, which in turn requires greater technology than the use of stone.
The first civilizations had a much smaller availability of different materials than the more technical civilizations. Initially, only natural or semi-natural materials were available such as stones, wood, clay, skins, etc. Non-precious metals are rarely found in nature, but are in mineral forms and a process of separation of the pure metal from the corresponding mineral is required. Over time, in various areas of the planet, techniques were developed to produce materials with new properties superior to those of natural materials (mainly alloys).
It has only been relatively recently that scientists have come to understand the relationship between structural elements of materials and their properties. This knowledge, acquired in the last approximately 200 years, has enabled them, to a high degree, to modify or adapt the characteristics of materials. Perhaps one of the most relevant scientists in this field has been Willard Gibbs when he demonstrated the relationship between the properties of a material and its microstructure.

Introduction
Materials science is the scientific discipline responsible for investigating the relationship between the structure and properties of materials. At the same time, it is worth clarifying that materials engineering is based on this, the properties-structure-processing-functioning relationships, and designs or projects some possible structure of the material, to achieve a predetermined set of properties.
Materials science is, therefore, a multidisciplinary field that studies fundamental knowledge about the macroscopic physical properties of materials and applies them in various areas of science and engineering, ensuring that they can be used in various works, machines and tools, or converted into products necessary or required by society. It includes elements of chemistry and physics, as well as chemical, mechanical, civil, electrical, medical, industrial, biological and environmental science engineering. With media attention focused on nanoscience and nanotechnology in recent years, materials science has been promoted in many universities.
Despite the spectacular progress in knowledge and development of materials in recent years, the permanent technological challenge requires increasingly sophisticated and specialized materials.
History
Historically, the development and evolution of societies have been closely linked to the ability of their members to produce and shape the materials necessary to satisfy their needs. Prehistorians have found it useful to classify early civilizations based on some of the materials used: Stone Age, Copper Age, Bronze Age or Iron Age. This last sequence seems universal in all areas, since the use of iron requires a more complex technology than that associated with the production of bronze, which in turn requires greater technology than the use of stone.
The first civilizations had a much smaller availability of different materials than the more technical civilizations. Initially, only natural or semi-natural materials were available such as stones, wood, clay, skins, etc. Non-precious metals are rarely found in nature, but are in mineral forms and a process of separation of the pure metal from the corresponding mineral is required. Over time, in various areas of the planet, techniques were developed to produce materials with new properties superior to those of natural materials (mainly alloys).
Tens of thousands of different materials with very special characteristics have been developed to meet the needs of our modern and complex society, these are metals, plastics, glass and fibers. One of the great revolutions in this science was the discovery of the different thermal phases of metals and, especially, steel. Currently the most sophisticated electronic advances are based on components called semiconductor materials.
The history of humanity has been closely linked to the type of materials that each society has developed. This is why several historical stages are known in this sense, without there necessarily being an exact date, or even occurring at different times in different human societies.
The Stone Age then refers to the period in which a particular human group used this material along with others of natural origin such as wood or bone predominantly. It is normally associated with a stage that is not technologically developed, which is not necessarily true, since cultures that achieved important cultural advances such as the Aztecs or the Mayans did not formally overcome the Stone Age, not because of a lack of advances, but because of the enormous variety of stone materials that these societies had, which largely met the needs they faced.
The bronze age, which some refer to as the "age of metals," refers to the use of metals and alloys, the importance of which lies in the fact that obtaining them requires the acquisition of complex metallurgical technologies. Bronze is the most famous of the alloys that history refers to to refer to the emergence of classical cultures and steel to the era of the industrial revolution.
The most recent eras are known as the “polymer era,” because their use is definitely due to highly complex advances in chemistry. Polymers can have virtually any physical property, so their use became so massive that it defines modern societies (plastic societies) very well.
However, history, like the development of materials, does not stop. Currently, composite materials, or composites, are prevailing. Formed by the union of others.
Classification
Materials science classifies all materials based on their properties and atomic structure. They are the following:
Another classification would be based on its properties, and it would be.
The latter include materials used in the electrical, electronic, computer and telecommunications industries:
Some books make a more exhaustive classification, although with these categories any element can be classified.
In reality, in materials science, only metals, ceramic materials and polymers are recognized as categories; any material can be included in one of these categories, so semiconductors belong to ceramic materials and composite materials are nothing more than mixtures of materials belonging to the main categories.
Applications and relationship with the industry
Radical advancement in materials technology can lead to the creation of new products or the flourishing of new industries, but today's industries in turn need materials scientists to scale up improvements and pinpoint possible breakdowns in the materials in use. The industrial applications of materials science include the choice of material, its cost-benefit to obtain said material, processing techniques and analysis techniques.
In addition to the characterization of the material, the materials scientist or engineer (although there is a difference, many times the engineer is a scientist or vice versa) must also deal with the extraction and its subsequent conversion into useful materials. Ingot molding, casting techniques, blast furnace extraction, electrolytic extraction, etc., are part of the knowledge required of a metallurgical engineer or an industrial engineer "Industrial Engineering (Spain)") to assess the capabilities of said material.
Leaving aside metals, polymers and ceramics are also very important in materials science. Polymers are a primary material used to shape or manufacture plastics. Plastics are the final product after various polymers and additives have been processed and formed into their final form. PVC, polyethylene, etc., are examples of plastics.
Regarding ceramics, clay can be mentioned, as well as its modeling, drying and firing to obtain a refractory material.
Basics
A material is defined as a substance (in most cases a solid, but other condensed phases may be included) that is intended for certain applications.[1] There are a myriad of materials around us; They can be found on anything from buildings and cars to spaceships. The main classes of materials are metals, semiconductors, ceramics and polymers.[2] New and advanced materials being developed include nanomaterials, biomaterials,[3] and energy materials to name a few.
The basis of materials science is the study of the interaction between the structure of materials, the processing methods to manufacture that material, and the resulting properties of the material. The complex combination of these factors produces the performance of a material in a specific application. The performance of a material depends on many characteristics across many length scales, from the chemical elements of which it is composed to its microstructure and macroscopic processing characteristics. Along with the laws of thermodynamics and kinetics&action=edit&redlink=1 "Kinetics (physics) (not yet written)"), materials scientists aim to understand and improve materials.
Scopes
Materials science covers many topics, from atomic structure, properties of different materials, processes and treatments. This would be a large-scale summary:

La ciencia de los materiales es un área de investigación muy activa. Junto con los departamentos de ciencia de materiales, física, química y muchos departamentos de ingeniería están involucrados en la investigación de materiales. La investigación de materiales cubre una amplia gama de temas; la siguiente lista no exhaustiva destaca algunas áreas de investigación importantes.
Nanomaterials
Nanomaterials describe, in principle, materials of which a single unit has a size (in at least one dimension) between 1 and 1000 nanometers (10 m), but is typically 1-100 nm. Nanomaterials research takes a materials science-based approach to nanotechnology, using advances in metrology and materials synthesis, which have been developed in support of microfabrication research. Materials with nanoscale structure often have unique optical, electronic, or mechanical properties. The field of nanomaterials is loosely organized, like the traditional field of chemistry, into organic (carbon-based) nanomaterials, such as fullerenes, and inorganic nanomaterials based on other elements, such as silicon. Examples of nanomaterials include fullerenes, carbon nanotubes, nanocrystals, etc.
Biomaterials
A biomaterial is any matter, surface or construction that interacts with biological systems. The study of biomaterials is called "biomaterials science." It has experienced consistent and strong growth throughout its history, with many companies investing large amounts of money in the development of new products. Biomaterials science encompasses elements of medicine, biology, chemistry, tissue engineering, and materials science.
Biomaterials can be derived from nature or synthesized in a laboratory using a variety of chemical approaches using metallic components, polymers, bioceramics or composite materials. They are often intended or adapted for medical applications, such as biomedical devices that perform, augment, or replace a natural function. Such functions may be benign, such as being used for a heart valve, or they may be bioactive with more interactive functionality such as hydroxyapatite hip implants. Biomaterials are also used every day in dental applications, surgery and drug delivery. For example, a pharmaceutical-impregnated construct can be placed in the body, allowing for sustained release of a drug over an extended period of time. A biomaterial can also be an autograft, allograft, or xenograft used as an organ transplant material.
Electronic, optical and magnetic
Semiconductors, metals and ceramics are used today to form very complex systems, such as electronic integrated circuits, optoelectronic devices, and magnetic and optical mass storage media. These materials form the basis of our modern computing world and therefore research into these materials is of vital importance.
Semiconductors are a traditional example of this type of materials. They are materials that have properties intermediate between conductors") and insulators&action=edit&redlink=1 "Insulator (electricity) (not yet drafted)"). Their electrical conductivities are very sensitive to the concentration of impurities, allowing the use of doping&action=edit&redlink=1 "Doping (semiconductor) (not yet drafted)") to achieve desirable electronic properties. Semiconductors therefore form the basis of traditional computing.
This field also includes new areas of research such as superconducting materials, spintronics, metamaterials, etc. The study of these materials involves knowledge of materials science and solid state physics or condensed matter physics.
Computational materials science
With continued increases in computing power, it has become possible to simulate the behavior of materials. This allows materials scientists to understand behavior and mechanisms, design new materials, and explain properties that were not well understood before. Efforts around integrated computational materials engineering now focus on combining computational methods with experiments to dramatically reduce the time and effort to optimize material properties for a given application. This involves simulating materials at all length scales, using methods such as density functional theory, molecular dynamics, Monte Carlo, dislocation dynamics, phase field, finite element, and many more.
