Heat treatment is to heat the metal material to a certain temperature. After a certain period of time, it is cooled to room temperature or lower at a certain speed. Thereby improving the material structure and obtaining materials with excellent performance. Generally, it refers to the treatment of metal materials, especially steel. The technique involves heating or cooling. Often extreme temperatures, to get the desired result. Such as hardening or softening of metals.
Metal heat treatment is one of the important processes in machinery manufacturing. Compared with other processes, heat treatment generally does not change the shape and chemical composition of the workpiece. Instead, it changes the microstructure inside the workpiece or changes the chemical composition of the workpiece surface. In order to give or improve the performance of the workpiece. Its characteristic is to improve the intrinsic quality of the workpiece. And the process is not visible to the naked eye.
Common heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering and quenching. In fact, the term heat treatment applies only to the process of heating and cooling. The goal is to change properties. But, heating and cooling sometimes occur as incidental stages to other manufacturing methods. Such as thermoforming or welding.
Heat treatment is primarily associated with increasing material strength. It can also be used to alter certain manufacturing goals. For example, improving machining, improving formability, restoring ductility after cold working operations. So, it is a very favorable manufacturing process. It can also improve product performance by increasing strength or other properties.
