stress-softening process的意思|示意

Hardness can do 61 — 65hrc maturation process is: annealing, softening after casting machining, machining of air cooling after quenching and low temperature stress tempering.

硬度能做到61——65hrc成熟工艺是：铸造后软化退火，便于加工，加工后空冷淬火加低温去应力回火。

The model can reflect the softening characteristics and whole process of rock's deformation and failure, and the influences of surrounding stress on rock's strength.

该模型能反映岩石的软化特性及破坏的全过程，也能反映岩石强度受围压的影响。
