摘要(Abstract)：

利用大块非晶在过冷液相区间具有较好的热塑性成形特点,选择锆基非晶Zr60Cu25Al10Fe5和纯Cu,在Zr基非晶过冷液相区内选择合适温度进行热压获得铜/非晶层状复合材料。通过X射线衍射(XRD)、扫描电镜(SEM)和能谱分析仪对该层状复合材料的界面形貌、成分分布以及非晶层的组织稳定性进行了研究,并对所制备的Zr基非晶/Cu层状复合材料室温压缩性能进行测试。结果表明:在温度为693 K,外载荷为150 MPa下,保温90 min,可以制备出Zr基非晶/Cu层复合材料,该复合材料的非晶层没有发生晶化,界面形成了一层原子扩散层,达到了良好的结合,该层状复合材料的压缩强度为850 MPa,并表现出一定的室温塑性,其室温强度满足复合材料的混合定律。
