摘　　要：Using melt infiltration casting at different temperatures （965, 990 and 1015 °C） for different time （10 and 15 min）, the composites of （Cu50Zr43Al7）99.5Si0.5 bulk metallic glass reinforced with tungsten wires were produced. X-ray diffraction （XRD）, scanning electron microscopy （SEM） and quasi-static compression tests were carried out to evaluate the microstructure and mechanical properties. The results show that the maximum ultimate compressive strength and strain-to-failure of about 1880 MPa and 16.7% were achieved, respectively, at the infiltration temperature of 965 °C for 15 min.在不同的温度(965,990和1015°C)和时间(10和15 min)下,使用熔体渗透铸造制备钨丝增强的(Cu50Zn43Al7)99.5Si0.5块体非晶复合材料。通过X射线衍射、扫描电镜和准静态压缩实验表征材料的显微组织和力学性能。结果表明:在渗透温度为965°C下保温15 min时制备的非晶复合材料,获得的最大极限抗压强度和失效应变分别为1880 MPa和16.7%。
