6061铝型材双级时效工艺的研究姜珊,李宏常,杨俊林,赵钰锋,王爽辽宁忠旺集团有限公司摘 要:利用拉伸性能测试,电导率测试,晶间腐蚀试验等手段,研究了双级时效工艺对6061合金组织与性能的影响.结果表明,6061铝型材双级时效后组织和性能良好,满足标准要求,各项性能与峰值时效175℃×8 h相当.其中,170℃×1.5 h+210℃×1.5 h制度下6061合金的综合力学性能优于峰值时效.随着预时效温度的升高,电导率呈上升趋势,180℃×1.5 h+210℃×1.5 h处理后电导率最高,腐蚀形貌由晶间腐蚀变为点蚀,腐蚀深度明显变浅.6061铝型材最优双级时效工艺为170℃×1.5 h+210℃×1.5 h,该制度能有效缩短生产周期,减少能耗,且使型材的力学性能,抗晶间腐蚀性能均优于峰值时效的性能......
