| 摘 要： | 用Mg-4%Si合金、纯Cu、纯Mg、Cu-38%Y合金经普通铜模铸造方法制备了一种原位颗粒增强Mg60Cu30Y10块体非晶合金复合材料。运用XRD以及EDS确定其颗粒为CuYSi相,采用SEM-EDS对颗粒的形貌、大小及成分进行了分析,并对Mg60Cu30Y10块体非晶合金复合材料的硬度及热稳定性进行了研究。结果表明,原位生成的CuYSi颗粒尺寸细小(10μm左右),形状规整并且均匀分布在非晶合金基体上;与Mg60Cu30Y10块体非晶合金相比,CuYSi颗粒的生成使得非晶合金复合材料的硬度增加102.5HV,ΔTx增加6.1K。

| Abstract: | By traditional copper casting method,a kind of in situ particle reinforced bulk Mg60Cu30Y10 amorphous alloy matrix composite was prepared from Mg-Si(4%) alloy,pure Cu,pure Mg and Cu-Y(38%) alloy.Particles in the amorphous alloy matrix composite were determined as CuYSi by XRD and EDS.The morphology,size and composition of the particles were analysised by SEM-EDS.Hardness and thermal stability of the bulk Mg60Cu30Y10 amorphous alloy matrix composite were studied.The results show that the in situ synthesized crystalline CuYSi particles with small size uniformly distribute in the amorphous alloy matrix composite.Compared with pure Mg60Cu30Y10 amorphous alloy,the hardness increased 102.5HV,the ΔTx of the composite increased 6.1K. |
