Heat Treatment Process Characteristics
Oct 22, 2016

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. Its characteristic is to improve the immanent quality of workpiece, which generally is not visible to the naked eye can see.
To make the metal workpiece with desired mechanical properties, physical properties and chemical properties, in addition to the reasonable choice materials and various forming process, heat treatment process is often essential. Steel is the most widely used material in mechanical industry, iron and steel complex, microstructure can be achieved by heat treatment to control, so the steel heat treatment is the main content of metal heat treatment. In addition, aluminum, copper, magnesium, titanium and its alloys are also can through the heat treatment to change its mechanical, physical and chemical properties, for the use of different performance.
