摘要：
The amorphous alloy (Zr0.55Cu0.3Al0.1Ni0.05)100-xErx (x=0, 0.5, 1, 2, 3, 4, 5) with a diameter of 3mm was prepared by water-cooled copper crucible smelting and copper mold aspiration casting. The mechanical properties of the amorphous alloy with Zr55Cu30Al10Ni5 added with different Er elements were studied by scanning electron microscopy (SEM), X-ray diffractometry (XRD) and mechanical properties test. The results show that the plasticity and fracture strength of Zr55Cu30Al10Ni5 amorphous alloy increases first and then decreases with the addition of Er. The composition (Zr0.55Cu0.3Al0.1Ni0.05)98Er2 amorphous alloy has the highest compressive strength σbc (2194.4 MPa), the highest fracture strength σc (2176.0 MPa) and the highest plastic εp (14.31%) at room temperature. The plasticity of the alloy at room temperature is 9.3 times as that of the alloy without Er, indicating that the addition of Er can improve the strength and plasticity at room temperature. © 2021, China Science Publishing & Media Ltd.
