Abstract在电弧炉中利用吸铸法制备了直径1-4 mm的原位生成TiC和β-Ti枝晶联合增强的块状Cu47Ti34Zr11Ni8非晶合金复合材料.DSC热分析结果表明,原位生成TiC颗粒的引入,没有影响基体合金的非晶形成能力.用OM,XRD,SEM,EDS等方法研究了复合材料的相组成、微观组织以及成分分布,结果表明,TiC颗粒作为异质形核中心促进了β-Ti枝晶的形成,形成了TiC颗粒和β-Ti枝晶联合增强的块状Cu47Ti34Zr11Ni8非晶合金复合材料,而且β-Ti枝晶的尺寸和数量与TiC颗粒的多少以及试样的尺寸有关.室温压缩试验表明,同单相非晶合金相比,块状Cu47Ti34Zr11Ni8非晶合金复合材料提高了抗压强度及塑性.
