时效制度对LC52铝合金组织与性能的影响
Effects of Ageing Treatment on Structure and Properties of LC52 Aluminum Alloy
【摘要】 研究了在单级时效、双级时效、回归再时效 (RRA)处理条件下 ,LC5 2铝合金的微观组织、室温力学性能、抗剥落腐蚀性能和应力腐蚀开裂敏感性。结果表明 ,LC5 2铝合金经 12 0℃× 2 4h +2 5 0℃× 2min(油浴 ) +12 0℃×30h回归再时效处理后 ,具有良好的综合性能
【Abstract】 The microstructure,mechanical properties at room temperature, exfoliation corrosion resistance and the stress-corrosion-cracking sensitivity of LC52 aluminum alloy were studied under different ageing processes. The results show that after retrogression and re-aging at 120℃×24h+250℃×2min(oil bath) +120℃×30h,the alloy possesses good comprehensive properties.
