Abstract

添加陶瓷增强相，可有效改善Mg-Al合金的高温性能。通过搅拌铸造法添加增强颗粒成本低且可制备大尺寸铸锭，具有良好的工业化前景。在过去的20年里，AZ31的蠕变行为和蠕变机制得到了广泛的研究，人们对其蠕变行为和蠕变机制有了一定的认识。但AZ31基复合材料的蠕变研究几乎没有开展的报道，特别是搅拌铸造法制备的AZ31基复合材料的蠕变研究尚为空白。本文对比观察了半固态搅拌铸造的SiC_p/AZ31复合材料以及铸态基体AZ31合金的微观组织，研究增强颗粒的加入对基体晶粒度和β-Mg₁₇Al₁₂相析出行为的影响。对比测试了铸态的AZ31合金和SiC_p/AZ31复合材料的抗蠕变性能，利用线性外推法和双对数曲线外推法综合比较，确定了门槛应力的大小，从而判明了复合材料的蠕变机制。
