摘要: 用吸铸法制备出含Ti(Zr)固溶体韧性相的Ti--Zr--Ni准晶合金棒,通过维氏显微硬度测定和单向压缩实验等方法研究了该新型合金的室温力学性能和断裂行为.结果表明：Ti--Zr--Ni准晶基复相(α--Ti(Zr)+I)合金力学性能良好, 维氏显微硬度值接近5.5 GPa, 断裂强度达到1000 MPa,Young's模量值23---36 GPa. 其中, Ti60Zr25Ni15合金的室温弹性应变可达4.2 %, 是Al基准晶合金的4倍. 但其室温单向压缩时的断裂方式仍为准解理断裂, 属脆性断裂

Abstract：Bulk Ti--Zr--Ni quasicrystals (QCs) were prepared by using conventional suction casting method. The characterization on their mechanical properties has been carried out by means of indentation and compression tests at room temperature. The strength indices of the icosahedral phase (I--phase)—based duplex phase alloy (α--Ti(Zr)+I phase) are 5.5 GPa in hardness and 1000 MPa in fracture strength, respectively. The Young's modulus is in the range of 23---36 GPa. The as--castTi60Zr25Ni15 QC--based composite alloy exhibits an elastic deformation capability of 4.2 % under a monaxial compression, which is about 4 times as large as that of Al—based QCs. The quasi--cleavage fracture morphologies indicate the bulk QC--based composite alloys to be brittle fracture.
