residual internal stress

Heat treatment methods, such as solid solution and quenching, have greatly enhanced its mechanical strength, which also leave a large internal residual stress in it.

固溶、淬火等热处理手段极大地提高了其机械强度，但同时使其内部产生了较大的残余应力。

Residual stress is a internal stress that commonly exists in material, how to measure that is very concerned by many scientists.

残余应力是普遍存在于材料中的一种内应力，如何测定其分布，一直是国内外很多学者关注的问题。

The results showed that it was viable to use CSR measuring creep internal stress of high temperature components and effective to forecast residual life of high temperature components using …

结果表明，用CSR法测定高温构件的蠕变内应力是可行的，将蠕变内应力用于高温构件的剩余寿命预测是有效的，并可克服一般外推方法的不足。
