The materials technology is an engineering science. It is concerned with materials, which are conditions for the building of machines, plants and apparatuses. The predominantly empirically won realizations of the materials technology make the developments possible of materials according to the chemical and physical characteristics, for example tensile strength, corrosion resistance, hardness or ductility and/or brittleness of steel, demanded by the industry, other metals, their alloys, ceramic(s) and polymers as well as composite materials.
A substantial subrange of the materials technology is the testing of materials. For the practical execution of testings of materials are trained. Similarly to it the occupation of the building material examiner for the range of the building material examination exists. Thereby over in each case nationally recognized teaching professions act with a regular training duration of 3 1/2 years.
The transition of natural materials such as bones, stone, clay/tone, wood, crust, ivory, hemp or leather to aimed won materials took place to end of the Jungsteinzeit with the beginning of the copper time around 4300 v. Chr., in which copper, gold and silver, later also lead and tin were won and worked on. Subsequently, the transition took place into the Bronzezeit approx. 2000 v. Chr., which was replaced from the Eisenzeit. Material-technically seen this only 1886 with the resound process was terminated, which made the industrial production of aluminum possible. Around 1930 the first polymer materials (plastics) in mass production were produced.
The materials technology covers the areas materials science and materials engineering as well as questions for the application of materials, material selection, the standardization and designation.
The structure of material can be differentiated with respect to atomistic structure, microstructure and basic structure. It has an internal structure and a surface texture.
For the analysis of the material different measuring procedures can be used.
