| Abstract Scope |
In recent years, titanium alloys designed to incorporate twinning induced plasticity (TWIP) and transformation induced plasticity (TRIP) have been studied for their potential to be a class of titanium alloys with excellent work hardening and ductility when compared with traditional titanium alloys such as Ti-6Al-4V. One disadvantage of these alloys is that they require a predominantly beta phase microstructure resulting in lower yield stresses than traditional alloys. In this work, solid solution strengthening and precipitation hardening via a novel heat treatment to form a low volume fraction, finely dispersed, alpha phase, have been combined to increase the yield strength of the TWIP/TRIP alloys while maintaining excellent work hardenability and ductility. Mechanical properties were determined. Detailed characterization of the resulting deformation substructure was performed using a combination of SEM, STEM, and CTEM techniques. |
