摘　　要：The glassy rods were successfully fabricated in the Cu-Zr-Ti-In alloy system by casting into a copper mold. The value of ATx reaches a maximum of 66 K for the BMG CusoZraTTi8In5 alloy. The reasons for enhancing glass forming ability of Cu-based BMGs with the addition of indium were discussed from atomic size and thermodynamics. Alternatively, the BMG Cu52Zra7Ti8In3 exhibits the highest compressive strength （1981 MPa） and the best plasticity among glassy Cu55-xZra7TisInx （x_〈5）. The total plastic deformation of Cu52Zr37TisIn3 before fracture approaches 1.2%.利用铜模吸铸法合成Cu-Zr-Ti-In非晶棒。块体非晶合金Cu50Zr37Ti8In5的ΔT x值最大,为66 K。从原子尺寸大小和热力学角度分析在铜基非晶合金中添加适量In元素后能够提高其非晶形成能力的原因。在所测的块体非晶合金Cu55-x Zr37Ti8In x(x≤5)中,Cu52Zr37Ti8In3表现出最高的抗压强度(1981 MPa)和最佳的塑性,其在压缩断裂前的总塑性变形量约为1.2%。
