相变残余应力 phase transformation residual stress
During the quenching,uneven thermal stress and phase transformation stress often appears because of the non-uniform internal temperature distribution and microstructure transformation. The existence of these stresses will directly affect the properties and service life of parts.
在淬火冷却过程中,因为零件内部温度分布不均匀,组织转变过程不均匀等而形成了热应力和相变应力,这些应力的存在将直接影响零件的组织性能和使用寿命。
