摘要:

采用最大输出能量为12.5 J的Nd-YAG激光器对AZ31镁合金薄板进行激光冲击成形(LSF), 用高分辨率透射电镜分析和研究了试样冲击区表面状态和微观结构。结果表明: 在镁合金薄板LSF冲击区凹面出现了纹理清晰的周期性波纹结构, 波纹间距为纳米级, 在LSF过程中伴随着亚晶、纳米晶和形变孪晶的产生。分析了冲击凹面残余应力分布, 并探讨了LSF过程中镁合金形成表面波纹现象和纳米晶形成的原因。

Abstract：

Thin AZ31 magnesium alloy sheet is laser-shock-formed (LSF) by means of a Nd-YAG pulse laser beam with a maximum output energy of 12.5 J. The surface morphology and microstructure in the shocked zone were characterized by optical microscopy and high resolution transmission electron microscopy. The results show that, periodic ripple structure with clear texture and nanoscale space appeared on concave in LSF shocked zone, with which the growth of sub-grains, nanocrystallites and deformation twins might be accompanied. The distribution of residual stress in the shocked concave was analyzed, and the relevant mechanism concerning ripple phenomenon and nanocrystallites formation during LSF was also discussed.

Key words： metallic materials AZ31 magnesium alloy laser shock forming (LSF) surface ripple nanostructure residual stress
