摘　　要：非晶合金复合材料可以解决非晶合金室温脆性的问题,但其具有的高硬度、高强度的特点使之难以采用常规的机械加工手段进行成形,热塑性成形技术是制造非晶合金复合材料零件或构件的有效成形手段。基于非晶合金复合材料的热塑性成形,介绍了非晶合金复合材料在过冷液相区的热塑性变形行为,探讨了增强相形态、第二相体积分数、温度和应变速率对非晶合金复合材料热变形行为的影响,总结了常见的非晶合金复合材料的热塑性本构模型,介绍了非晶合金复合材料热塑性成形的典型工艺与方法,最后,展望了未来非晶合金复合材料热塑性成形研究的发展方向。Bulk metallic glass composites(BMGCs)can solve the problem of brittleness for bulk metallic glass at room-temperature,but its characteristics of high hardness and high strength make it difficult to form by conventional machining methods,so the thermoplastic forming technology is an effective forming method to manufacture bulk metallic glass composite parts or components.Therefore,on the basis of thermoplastic forming of bulk metallic glass composites,the thermoplastic deformation behavior of bulk metallic glass composites in the supercooled liquid region was investigated,and the influences of the morphology of reinforcement phase,the volume fraction of the second phase,the temperature and strain rate on the thermal deformation behavior of bulk metallic glass composites were investigated.Then,the common thermoplastic constitutive models of bulk metallic glass composites were summarized,and the typical forming processes and methods of bulk metallic glass composites were introduced.Finally,the future development direction of the research on the thermoplastic forming of bulk metallic glass composites was prospected.
