Influence of Processing Technology

 

Effect of Hot - working
Forging is a common hot - working process. During forging, the material undergoes repeated upsetting and drawing - out, and the internal microstructure becomes more compact and uniform, thereby increasing the hardness and tensile strength of the material. At the same time, parameters such as forging temperature and forging ratio also affect the final performance of the material. For example, an appropriate forging ratio can refine the grains and improve the mechanical properties of the material.

 

Hot - rolling can also improve the performance of the material. During hot - rolling, the material is rolled at a high temperature. By controlling parameters such as rolling temperature, rolling speed, and reduction amount, the microstructure of the material can be adjusted. For example, controlling the reduction amount can elongate the grains of the material along the rolling direction, forming a fibrous structure and increasing the strength of the material.

 

Effect of Cold - working
Cold - working processes such as cold - rolling and cold - drawing can cause work - hardening of the material. During cold - working, the grains of the material will be deformed and fragmented, and the dislocation density will increase, resulting in an increase in the hardness and tensile strength of the material. For example, the hardness and tensile strength of cold - rolled steel plates will significantly increase with the increase of the cold - rolling reduction amount. However, excessive cold - working may lead to a decrease in the toughness of the material and even the appearance of cracks.

Influence of Heat - treatment Technology

 

Effect of Quenching
Quenching is a rapid - cooling heat - treatment process. Through quenching, the austenite structure in steel can be transformed into a martensitic structure, thereby significantly increasing the hardness and strength of the material. For example, for some tool steels, the hardness can be significantly increased after quenching to meet the high - hardness requirements of cutting tools. However, the quenched steel is usually brittle and requires subsequent treatments such as tempering to improve the toughness.

 

Effect of Tempering
Tempering is a heat - treatment process carried out after quenching. Tempering can reduce the internal stress of the quenched steel and adjust the balance between the hardness and toughness of the material. For example, low - temperature tempering can slightly improve the toughness while maintaining a relatively high hardness; high - temperature tempering can reduce the hardness of the material, but the toughness is greatly improved.

 

Effect of Annealing
Annealing is mainly used to eliminate the internal stress of the material, improve the microstructure of the material, and increase the plasticity of the material. Full annealing can homogenize the material's microstructure, reduce the hardness, and improve the machinability of the material. For example, for some cold - rolled steel plates, after annealing treatment, the hardness will be reduced, facilitating subsequent processing such as stamping.
