摘要： 利用正交试验法,对Al-Cu-Mn合金半固态锻压件进行了固溶时效热处理.通过对硬度指标的分析,获得了热处理的最佳工艺参数.同时分析了时效后的显微组织.结果表明,Al-Cu-Mn合金半固态锻压件在固溶温度540℃、固溶时间13 h、时效温度165℃、时效时间8 h下,其维氏硬度值可达130 MPa以上;且析出相均匀、弥散地分布在基体上.

Abstract: Different solution-ageing processes were carried out by way of orthogonal experiment for the semi-solid Al-Cu-Mn alloy forgings. Then, the resultant hardnesses were analyzed to determine the optimal technological parameters in such a heat-treatment, with the microstructure after ageing discussed. It was revealed that the Vickers hardness number can come up to over 130 MPa if the temperature/time of solution hardening and of age hardening are 540°C/13 hr and 165°C/8 hr, respectively, with the precipitated phases distributed uniformly and dispersedly on the matrix.
