用逆向浸渗工艺制备了直径为0.5mm的钨丝增韧Zr41Ti14Cu12.5Ni10Be22.5块体非晶复合材料。研究了浸渗温度对复合材料界面状态以及压缩性能的影响。当浸渗温度分别为1000、1100和1200K时,复合材料的界面结合分别为机械结合、机械结合与冶金结合共存和反应结合形式。较低的浸渗温度会造成界面结合强度不足,过高的浸渗温度导致钨丝脱熔而形成界面反应产物,二者均对Zr41Ti14Cu12.5Ni10Be22.5块体非晶复合材料的压缩强度和变形行为产生不利影响。在1100K浸渗时、保温30min获得的W/Zr块体非晶复合材料具有2409MPa的最高压缩强度和19.5%的塑性变形能力。
Tungsten filament toughened Zr41Ti14Cu12.5Ni10Be22.5 bulk amorphous composite with a diameter of 0.5mm was prepared by reverse infiltration process. The effect of infiltration temperature on the interfacial state and compressive properties of the composites was investigated. When the infiltration temperature is 1000, 1100 and 1200K respectively, the interfacial bonding of the composites are mechanical bonding, coexistence of mechanical bonding and metallurgical bonding, and reactive bonding. The lower infiltration temperature will result in the lack of bonding strength at the interface. When the infiltration temperature is too high, the melting of the tungsten wire will lead to the formation of interfacial reaction products. Both of them have significant influence on the compressive strength and deformation of Zr41Ti14Cu12.5Ni10Be22.5 bulk amorphous composites The behavior has an adverse effect. When infiltrated at 1100K, the W / Zr bulk amorphous composite obtained after 30min holding has the highest compressive strength of 2409MPa and the plastic deformation capacity of 19.5%.
