本文研究了12Cr-3Ni-2Mo-V-Nb-N叶片钢高频淬火后的应力分布规律,并对此规律做出了解释。测量了高频淬火区、过度区、基材区在不同强度喷丸后残余应力沿层深的分布,对残余应力场特征进行了分析。结果分析表明相同工艺喷丸后淬火区与基材区有不同的残余应力场分布,在工艺中要兼顾两者才能得出最优的喷丸工艺。 In this paper, the stress distribution law of 12Cr-3Ni-2Mo-V-Nb-N blade steel after induction hardening has been studied and the rule has been explained. The distributions of residual stress along the layer depth after shot peening with different intensities were measured and the characteristics of residual stress field were analyzed. The results show that the same process after shot peening quenching zone and the substrate area have different residual stress field distribution, both in the process to give the best shot peening process.
