The effect of Ti content on the phase composition, microstructure manipulation and work-hardening behavior of ZrCu alloys during compression was investigated in this work. The results show that the phase composition, microstructure, mechanical properties and work-hardening ability of ZrCu alloys are very sensitive to Ti content. The introduction of Ti enhances the stability of the austenite phase and the amorphous forming ability of ZrCu alloys. The Zr45Cu50Ti5 alloy exhibited best comprehensive mechanical properties, its yield strength, ultimate compressive strength and fracture strain are 981 MPa, 1922 MPa and 16.9%, respectively. Zr49Cu50Ti1 and Zr47Cu50Ti3 alloys have the best work hardening ability under low strain, and the Zr43Cu50Ti7 alloy has the best work hardening ability under high strain. Finally, the austenite stabilization mechanism, strengthening mechanism and work hardening mechanism are revealed.
