用铜模吸铸法制备了Zr(65-x)Cu17.5Ni10Al7.5Fex(x=0,1,2,3,4,5,at%)块体合金,利用X射线衍射仪(XRD)、透射电镜(TEM)、同步热分析(DSC)、万能试验机和扫描电镜(SEM)研究了Fe对Zr基合金的非晶形成能力、热稳定性及力学性能的影响.结果表明:适量添加Fe元素有利于提高该合金的非晶形成能力和热稳定性,当Fe含量为x=2时,其内部结构为完全非晶结构,并且此成分具有较高的GFA和热稳定性(△Tx=58 K).Fe元素的适量加入也有利于提高该合金的强度和塑性,其中x=2的块体非晶合金的抗压强度σf、断裂应变εf和塑性应变εp分别高达2338 MPa、12.4%和2.0%.
