摘 要: 對(duì)LD10鋁合金加工后的去應(yīng)力處理工藝的殘余應(yīng)力用小孔釋放法進(jìn)行了測(cè)試, 對(duì)不同熱處理工藝和加工后的去應(yīng)力處理工藝對(duì)殘余應(yīng)力的影響進(jìn)行了分析。結(jié)果表明：加工以后使應(yīng)力重新分布和使殘余應(yīng)力降低或均勻化，冷熱循環(huán)去應(yīng)力處理效果很小。

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
