熔体渗透参数对钨丝增强（Cu50Zn43Al7）99.5Si0.5非晶复合材料显微组织和力学性能的影响

摘要

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%。%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.
