摘　　要：采用热等静压工艺制备了ZrH2/6063Al复合材料,对其在H2气氛中热处理,研究了热处理过程中基体Al合金与增强相ZrH2颗粒的界面反应特性,采用SEM和XRD分析了ZrH2/6063Al复合材料经热处理后的微观组织和相结构。结果表明:采用热等静压的方法可以制得较为致密的样品,且不会引起样品相结构的变化;在H2气氛中热处理时,Al与ZrH2反应生成Al3Zr。Hot isostatic pressing was used to prepare ZrH 2 /6063Al composite materials.The composites were then heat treated under hydrogen atmosphere,and interfacial reaction characteristic between Al matrixes and reinforcing phase particles ZrH 2 was investigated.SEM and XRD were used to analysis microstructure and phase structure of the heat-treated composites.The results show that hot isostatic pressing can prepare dense samples and will not cause change of phase structure of the sample.Al 3 Zr is produced through the reaction of Al and ZrH 2 during the heattreatment process in a hydrogen atmosphere.
