| Abstract Scope |
The design of titanium alloys with strength-ductility synergy is challenge to materials science. We propose an effective way to improve the comprehensive mechanical properties of titanium alloys based on the design of special structure of β+α phases by integrating phase field simulations and experiments. Phase field simulations have been used to screen the microstructure and guide the following experimental heat treatment process. Based on this design strategy, a Ti-1023 alloys with special microstructure of α phase in β matrix is designed, which show an enhanced ductility by ~50% and strength by ~10% simultaneously. Our work not only shed light on the design of novel Ti-alloys with comprehensive strength and ductility properties, but also propose a promising way to improve the mechanical properties of all the precipitated strength traditional materials. |
