Mechanism of cryogenic treatment

1. Elimination of retained austenite: generally, the retained austenite after quenching and tempering is about 8-20%, and the retained austenite will be further martensitized with the passage of time. In the process of martensite transformation, the volume expansion will be caused, which will affect the dimensional accuracy, and increase the stress inside the lattice, which… Read more Mechanism of cryogenic treatment
