Effect of heat treatment on microstructure and mechanical properties of laser deposited Ti60A alloy

Highlights
- Novel “Tβ-30 °C” and “Tβ-10 °C” duplex annealing was adopted, respectively.
- Microstructure and mechanical properties after heat treatments were compared.
- Room temperature ductility could be improved by 40%, from 10 ± 1% to 14 ± 3%.
- 600 °C/310 MPa stress rupture life could be improved by 24%, from 317 ± 12 h to 394 ± 16 h.
