Influence of laser shock peening times on microstructure and hardness of TA15 titanium alloy

  • 摘要: 采用脉冲能量20 J的调Q掺钕玻璃激光对钛合金TA15进行不同次数的激光冲击强化.结果表明,激光冲击强化使材料表面产生微塑性变形,形成致密的微凹坑,导致晶粒细化,并且随冲击次数的增加,其微凹坑的深度增加;但当冲击次数超过2次后,深度便不再增加.所以试验中的最高冲击次数为2次,而且在冲击次数为2次以内,材料位错密度也随冲击次数的增加而增加,并发生塞积、增殖、缠结等现象.表征在硬度方面,由于上述微观组织的变化,材料的硬度提高.随着冲击次数增加,材料的硬度增加并且激光冲击强化的影响层深度也随之增加.
