摘　　要：鉴于目前渗流铸造法制备的非晶复合材料的增强体单一,且难于成型复杂零件的局限性,提出了渗流铸造W纤维+WC颗粒混杂增强铜基非晶复合材料铸坯+过冷液相区压铸成型复杂零件的工艺路线,重点研究混杂增强非晶复合材料的增强机制和压铸过程复合材料的组织和力学性能的变化规律等,介绍钨碳等元素的添加对增强铜基块状非晶复合材料的研究进展现状。A processing preparing complex parts by melt infiltration casting of W-fibers and WC-particles hybride enhanced Cu-based amorphous composite ingot and by die casting in supercooled phase region is proposed due to single reinforcer of amorphous composites by infiltration casting and the difficulty in milding complex parts. Focus on enhancement mechanism for the hybrid reinforced amorphous composites and variation in microstructure and mechanical properties of die cast composites as well as research status in W reinforced bulk amorphous Cu-based composites are presented.
