：

研究时效时间和时效温度对6005A铝合金显微组织与力学性能的影响,对该铝合金挤压型材进行人工时效实验,时效时间分别为4、8和12h,时效温度分别为150、175和200℃.结果表明：随着时效温度和时间增加,挤压过程形成的粗大Al(Fe,Cr)Si析出相形貌由颗粒状向棒状转变,175℃时亚微米级析出相体积分数最大,200℃时在晶界析出1～3μm左右的AlFeSi相.挤压型材的室温力学性能对时效工艺中

模具参数对楔横轧铝合金轧件内部空洞的影响

通过分析楔横轧内部空洞(疏松)缺陷的物理性质和形成特征，将内部空洞视为多孔材料，利用多孔材料的刚塑性有限元方法，建立7075铝合金坯料内部空洞缺陷的数值模型。采用相对密度研究成形角、展宽角、断面收缩率对内部空洞缺陷的影响规律。结果显示：内部空洞的扩展主要发生在展宽段，楔入段对它的影响很小。展宽角是影响内部空洞产生的主要因素，而断面收缩率的影响较小。成形角、展宽角、断面收缩率越大，越不易发生内部空洞
