Heat treatment process characteristics
- Jun 25, 2018 -

Metal heat treatment is one of the important technology in mechanical manufacturing, compared with other processing technology, heat treatment generally does not change the shape of the workpiece and the chemical composition of the whole, but by changing the workpiece internal microstructure, or change the surface chemical composition, or improve the use performance of workpiece. It is characterized by improving the internal quality of the workpiece, which is generally not visible to the naked eye.

In order to make the metal workpiece have the required mechanical properties, physical properties and chemical properties, heat treatment technology is often necessary except the reasonable selection of materials and various forming processes. Steel is the most widely used material in the mechanical industry. Its microstructure is complex and can be controlled by heat treatment. Therefore, heat treatment of steel is the main content of metal heat treatment. In addition, aluminum, copper, magnesium, titanium and their alloys can also be modified by heat treatment to obtain different performance.
