In order to make more reasonable use of metal materials and give full play to its role, it is necessary to master the properties of components made of various metal materials under normal working conditions (service properties) and the properties of materials in the process of hot and cold processing (process properties).
The performance of materials includes physical properties (such as specific gravity, melting point, electrical conductivity, thermal conductivity, thermal expansion, magnetic properties, etc.), chemical properties (durability, corrosion resistance, oxidation resistance), and mechanical properties, also known as mechanical properties.
