利用铜模铸造的方法制备了(Zr41.2Ti13.8Ni10Be22.5)1-x/87.5Cu12.5+x (x=1.6,6,11.2)块体非晶合金及其复相组织,分析了合金的相组成、热稳定性、力学性能及断口形貌。结果表明:随着铜含量的不断增多,尽管过冷液相区(△Tx)逐渐增大,但非晶形成能力却不断下降。当合金的铜含量提高到 18.5%时,非晶合金的压缩断裂强度达到 2.2 GPa,进一步增加铜含量到 23.7%,压缩强度出现下降趋势。 The (Zr41.2Ti13.8Ni10Be22.5) 1-x / 87.5Cu12.5 + x (x = 1.6,6,11.2) bulk amorphous alloys and their complex phases were prepared by copper mold casting. Phase composition, thermal stability, mechanical properties and fracture morphology. The results show that with the increase of copper content, the formation ability of amorphous material decreases continuously although the supercooled liquid region (△ Tx) gradually increases. When the copper content of the alloy increased to 18.5%, the compressive breaking strength of the amorphous alloy reached 2.2 GPa, further increasing the content of copper to 23.7%, the compressive strength showed a downward trend.
