Abstract
The microstructure and mechanical properties of (Zr-Ti)1-χNiχ(χ =0, 1, 3, and 5 wt.%) alloys were studied. With the addition of nickel (Ni), the phase composition of alloys changes from α phase to α phase + hexagonal close packed (hcp) C14 Laves-phase. The thickness of lamellar α phase decreases with increasing Ni content. Optical microscopy and transmission electron microscopy results indicated that C14 Laves-phase is formed on the boundary. The Zr-Ti-3wt.%Ni alloys exhibits better ultimate compressive strength and compressive plasticity (1715 MPa and 9.70%) than that of Zr-Ti alloys (1598 MPa and 12.40%). The decrease of the average thickness of the lamellar α-phases (from 0.183 μm to 0.065 μm) leads to the improvement of the strength of the alloy. Additionally, the solid solution strengthening and the second phase strengthening are also important reasons for the improvement of the strength.
