The principle materials used for tools can be divided into three major categories: ferrous material, nonferrous material, and nonmetallic material.
Magnesium alloys are the lightest structural metallic materials, which can be used to reduce the weight of military equipments and improve their performance.
inorganic nonmetallic material
In this paper a new criterion for thermal fatigue damage was proposed to evaluate the thermal fatigue performances of metallic materials.
The aluminium-lithium alloy is a new light metallic material.
At the same time, with the corresponding cooling conditions, a method of granulation of metallic materials can be obtained.
Principle, method and apparatus for young's modulus measurement of metallic material by indentation method are reviewed, and the methods error is analysed.
Nonmetallic materials are those materials such as woods, plastics, rubbers, epoxy resins, ceramics and diamonds that do not have a metallic base.
The main cause of error of strain measurement using electronic extensometer and its effects on the strength measurement in tensile tests of metallic materials was analyzed.
Abstract: By the using of the theory of plastic mechanics, a calculated formula of ultimate strength of shearing stress is obtained for metallic materials with torsion of circular shaft, and the experimental results about low-carbon steel are given.
Series HV/ HVS Vickers Hardness Tester, that is composed of precision mechanism, optical system and electric technology, is used to measure Vickers hardness of either metallic materials or non-metallic materials.
Researchers are building the surfaces out of metallic materials on a substrate.
