摘　　要：综合运用X射线衍射、光学显微、扫描电镜、能谱分析等技术,系统地研究了一种铜锆合金(Cu_(47.2)Zr_(47.2)Cr_(0.6)Al_(5))合金锭经铜模快速冷凝后的压缩断裂行为。研究发现,该样品在压缩试验中发生的断裂为典型的脆性断裂,断裂起源于枝晶与含铝共晶相之间的晶界处。The fracture behavior in a CuZr-based alloy of Cu_(47.2)Zr_(47.2)Cr_(0.6)Al_(5) applying quick solidification technique is systematically studied by X-ray diffraction(XRD),optical morphology(OM),scanning electron microscope(SEM)and energy dispersive spectrometer(EDS).It is found that the fracture of this sample in compression test is a typical brittle fracture,which originates from the grain boundary between dendrite and eutectic phase containing aluminum.
