Effect of Cold Working on the Properties and Microstructure of Cu-3.5 wt% Ti Alloy
Abstract
:1. Introduction
2. Experimental Procedure
3. Results
4. Discussion
5. Conclusions
- Cu-3.5Ti alloys were strengthened by the β’-Cu4Ti metastable phase during aging, with the extension of the aging time, the metastable phase transformed into the equilibrium β-Cu4Ti phase.
- Deformation after aging would cause the metastable phase to dissolve into the matrix, and the twins and slip bands generated during deformation would accelerate the precipitation of the metastable β’-Cu4Ti phase in aging treatment, reduce the precipitation of β’-Cu4Ti phase temperature of the precipitation phase, and make the β’-Cu4Ti phase finer.
- The optimal heat treatment is 500 °C for 2 h + 70% deformation + 450 °C for 2 h, the corresponding conductivity and hardness are 13.88% IACS and 340.78 Hv.
