摘要
利用高能超声复合法及超声稀释原位反应烧结块制备了SiCp/ZA27复合材料(SiC颗粒最小平均直径为0.5μm)和(TiAl3、Al2O3及TiB2)/ZA27复合材料,增强相在基体分布均匀,复合材料界面结合良好。依据超声波对熔体作用时的空化和声流效应,分别讨论了SiCp/ZA27的界面润湿机制和烧结块快速稀释的原理。
Two types of composites SiCJZA27（average minimal size of SiC particles is 0.51μm） and （TiAl3, Al2O3, TiB2）/ZA27 were separately prepared by high intensity ultrasonic compound and high intensity ultrasonic dilution of the XD composite, with reinforcement phases distributed homogeneously in matrix. Based on the effects of cavitation and acoustic streaming caused by ultrasound propagating in melt, the mechanisms for the wettability between SiCpZA27 interface and the quick dilution of the XD composites were discussed.
