摘要

建立了一种新的残余应力测量方法，并在反向推导的基础上推导出了残余应力的表达式。试验结果表明，熔覆层上层残余应力以拉应力形式存在，熔覆层与基体过渡区残余应力以压应力形式存在。

Research of measuring residual stress in laser cladding with anisotropic material based on reverse deduce

New method of residual stress measurement is established and expressions are inferred based on reverse deduce. Test results show that residual stress in the upper layer presents as tensile stress, while presents as compressive stress in the transition zone between laser cladding and substrate.
