摘要

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。

Abstract

Tungsten wire with 0.5 mm in diameter toughened Zr41Ti14Cu12.5Ni10Be22.5 bulk amorphous composites were prepared by reverse infiltration technology. Effects of infiltrated temperature on interface and compression behavior of the composites were investigated. Interface of the composites exhibit the features of mechanical bonding

co-existence of mechanical bonding and metallurgical bonding and reactive bonding

respectively

at 1 000 K

1 100 K and 1 200 K. The bonding strength is decreased with the lower infiltrated temperature

while interface reactive product can be formed with the higher infiltrated temperature as a result of W wire melting

which is harmful for the compression strength and deformation behavior of the composites. The Wf/Zr-based bulk amorphous composites with 2 409 MPa in maximum compressive strength and 19.5% in plastic deformation can be obtained with infiltrated temperature of 1100 K for 30 min.
