properties of matter and its applications to various areas of science and This science investigates the relationship between the structure of materials and their It includes elements of applied physics and chemistry, as well as chemical, mechanical, civil and electrical With significant media attention to nanoscience and nanotechnology in recent years, materials science has been propelled to the forefront at many It is also an important part of forensic engineering and forensic materials engineering, the study of failed products and HistoryThe material of choice of a given era is often its defining point; the Stone Age, Bronze Age, and Steel Age are examples of Materials science is one of the oldest forms of engineering and applied science, deriving from the manufacture of Modern materials science evolved directly from metallurgy, which itself evolved from A major breakthrough in the understanding of materials occurred in the late 19th century, when Willard Gibbs demonstrated that thermodynamic properties relating to atomic structure in various phases are related to the physical properties of a Important elements of modern materials science are a product of the space race: the understanding and engineering of the metallic alloys, and silica and carbon materials, used in the construction of space vehicles enabling the exploration of Materials science has driven, and been driven by, the development of revolutionary technologies such as plastics, semiconductors, and Before the 1960s (and in some cases decades after), many materials science departments were named metallurgy departments, from a 19th and early 20th century emphasis on The field has since broadened to include every class of materials, including: ceramics, polymers, semiconductors, magnetic materials, medical implant materials and biological [edit] Fundamentals of materials scienceIn materials science, rather than haphazardly looking for and discovering materials and exploiting their properties, one instead aims to understand materials fundamentally so that new materials with the desired properties can be The basis of all materials science involves relating the desired properties and relative performance of a material in a certain application to the structure of the atoms and phases in that material through The major determinants of the structure of a material and thus of its properties are its constituent chemical elements and the way in which it has been processed into its final These, taken together and related through the laws of thermodynamics, govern a material’s microstructure, and thus its An old adage in materials science says: "materials are like people; it is the defects that make them interesting" The manufacture of a perfect crystal of a material is currently physically Instead materials scientists manipulate the defects in crystalline materials such as precipitates, grain boundaries (Hall-Petch relationship), interstitial atoms, vacancies or substitutional atoms, to create materials with the desired Not all materials have a regular crystal Polymers display varying degrees of crystallinity, and many are completely non- Glasses, some ceramics, and many natural materials are amorphous, not possessing any long-range order in their atomic The study of polymers combines elements of chemical and statistical thermodynamics to give thermodynamic, as well as mechanical, descriptions of physical In addition to industrial interest, materials science has gradually developed into a field which provides tests for condensed matter or solid state New physics emerge because of the diverse new material properties which need to be [edit] Materials in industryRadical materials advances can drive the creation of new products or even new industries, but stable industries also employ materials scientists to make incremental improvements and troubleshoot issues with currently used Industrial applications of materials science include materials design, cost-benefit tradeoffs in industrial production of materials, processing techniques (casting, rolling, welding, ion implantation, crystal growth, thin-film deposition, sintering, glassblowing, ), and analytical techniques (characterization techniques such as electron microscopy, x-ray diffraction, calorimetry, nuclear microscopy (HEFIB), Rutherford backscattering, neutron diffraction, )Besides material characterisation, the material scientist/engineer also deals with the extraction of materials and their conversion into useful Thus ingot casting, foundry techniques, blast furnace extraction, and electrolytic extraction are all part of the required knowledge of a metallurgist/ Often the presence, absence or variation of minute quantities of secondary elements and compounds in a bulk material will have a great impact on the final properties of the materials produced, for instance, steels are classified based on 1/10th and 1/100 weight percentages of the carbon and other alloying elements they Thus, the extraction and purification techniques employed in the extraction of iron in the blast furnace will have an impact of the quality of steel that may be The overlap between physics and materials science has led to the offshoot field of materials physics, which is concerned with the physical properties of The approach is generally more macroscopic and applied than in condensed matter See important publications in materials physics for more details on this field of The study of metal alloys is a significant part of materials Of all the metallic alloys in use today, the alloys of iron (steel, stainless steel, cast iron, tool steel, alloy steels) make up the largest proportion both by quantity and commercial Iron alloyed with various proportions of carbon gives low, mid and high carbon For the steels, the hardness and tensile strength of the steel is directly related to the amount of carbon present, with increasing carbon levels also leading to lower ductility and The addition of silicon and graphitization will produce cast irons (although some cast irons are made precisely with no graphitization) The addition of chromium, nickel and molybdenum to carbon steels (more than 10%) gives us stainless Other significant metallic alloys are those of aluminium, titanium, copper and Copper alloys have been known for a long time (since the Bronze Age), while the alloys of the other three metals have been relatively recently Due to the chemical reactivity of these metals, the electrolytic extraction processes required were only developed relatively The alloys of aluminium, titanium and magnesium are also known and valued for their high strength-to-weight ratios and, in the case of magnesium, their ability to provide electromagnetic These materials are ideal for situations where high strength-to-weight ratios are more important than bulk cost, such as in the aerospace industry and certain automotive engineering Other than metals, polymers and ceramics are also an important part of materials Polymers are the raw materials (the resins) used to make what we commonly call Plastics are really the final product, created after one or more polymers or additives have been added to a resin during processing, which is then shaped into a final Polymers which have been around, and which are in current widespread use, include polyethylene, polypropylene, PVC, polystyrene, nylons, polyesters, acrylics, polyurethanes, and Plastics are generally classified as "commodity", "specialty" and "engineering" PVC (polyvinyl-chloride) is widely used, inexpensive, and annual production quantities are It lends itself to an incredible array of applications, from artificial leather to electrical insulation and cabling, packaging and Its fabrication and processing are simple and well- The versatility of PVC is due to the wide range of plasticisers and other additives that it The term "additives" in polymer science refers to the chemicals and compounds added to the polymer base to modify its material Polycarbonate would be normally considered an engineering plastic (other examples include PEEK, ABS) Engineering plastics are valued for their superior strengths and other special material They are usually not used for disposable applications, unlike commodity Specialty plastics are materials with unique characteristics, such as ultra-high strength, electrical conductivity, electro-fluorescence, high thermal stability, It should be noted here that the dividing line between the various types of plastics is not based on material but rather on their properties and For instance, polyethylene (PE) is a cheap, low friction polymer commonly used to make disposable shopping bags and trash bags, and is considered a commodity plastic, whereas Medium-Density Polyethylene MDPE is used for underground gas and water pipes, and another variety called Ultra-high Molecular Weight Polyethylene UHMWPE is an engineering plastic which is used extensively as the glide rails for industrial equipment and the low-friction socket in implanted hip Another application of material science in industry is the making of composite Composite materials are structured materials composed of two or more macroscopic An example would be steel-reinforced concrete; another can be seen in the "plastic" casings of television sets, cell-phones and so These plastic casings are usually a composite material made up of a thermoplastic matrix such as acrylonitrile-butadiene-styrene (ABS) in which calcium carbonate chalk, talc, glass fibres or carbon fibres have been added for added strength, bulk, or electro-static These additions may be referred to as reinforcing fibres, or dispersants, depending on their
