Heat treatment methods, such as solid solution and quenching, have greatly enhanced its mechanical strength, which also leave a large internalresidualstress 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。

Residualstress 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。
