LD10铝合金残余应力测试及分析
(西南交通大学, 成都 610031)
摘 要: 对LD10铝合金加工后的去应力处理工艺的残余应力用小孔释放法进行了测试, 对不同热处理工艺和加工后的去应力处理工艺对残余应力的影响进行了分析。结果表明：加工以后使应力重新分布和使残余应力降低或均匀化，冷热循环去应力处理效果很小。

TEST AND ANALYSIS OF RESIDUAL STRESS OF ALLOY ALUMINIUM LD10
（Southwest Jiaotong University, Chengdu 610031）
Abstract:The test of residual stress of stress-relief treatment after machining with the small hole releasing way was carried out and the effect of different heat-treated and stress-relief technique after machining on residual stress was analyzed. The results indicated that after machining the stress is re-arranged and the residual stress decreases; the effect of thermal cycle stress-relief-treatment is little.
Key words: alloy-aluminium machining stress-relief treatment residual stress
