The superstrength of 65Mn spring steel obtained by proper quenching and tempering under ultrafine grain conditions

In recent years, researchers have found that by using ultrafine grain conditions during quenching and tempering, the superstrength of 65Mn spring steel can be obtained. Ultrafine grain conditions mean that the grain size of the material is refined to a nanoscale level, which can significantly improve the strength of the material.

During the quenching process, the 65Mn spring steel is heated to a high temperature and then rapidly cooled in a specialized quenching medium. The ultrafine grain conditions are achieved in the tempering stage by using a specific temperature and time.

The superstrength of the 65Mn spring steel obtained by this process is due to the excellent combination of strength and toughness. The ultrafine grain structure provides a large number of grain boundaries, which can effectively inhibit the movement of dislocations and improve the strength of the material. At the same time, the increased number of bond interfaces between the grains can improve the toughness of the material.

In addition, the superstrength of the 65Mn spring steel obtained by proper quenching and tempering under ultrafine grain conditions has other advantages, such as increased wear resistance, improved fatigue resistance, and reduced deformation. These benefits are significant in many applications, such as in the manufacturing of various mechanical parts and components.
