摘　　要：主要研究搅拌摩擦焊接时焊接参数对LF5合金力学性能的影响,结果表明:当ω为定值时,随着ω/v值的增加,强度和塑性值都增加,在达到最大后,塑性值到达峰值,继续增加ω/v值,强度和塑性反而下降。当ω/v为定值时,随着ω的增加,机械性能提高。并发现焊接接头性能的高低,除了和ω/v有关外,还和ω的绝对值有关。In this paper we mainly study the effect of Friction Stir Welding parameters on LF5alloy mechanics properties.Experiment results shows that whenωis constant ,strength and plasticity increase withω/v,when mechanic property attain the maximal value,the strength and plasticity will decrease with the increase ofω/v.Whenω/v is constant ,mechanical properties heighten with the increase ofω.Discovered that the joints property not only have relation withω/v,but also have relation with the absolute value ofω.
