The phase and TTT diagrams of the Ti-6Al-4V system allow the development of a new quenching forming process for a more energy and material efficient production of sheet metal parts. This new process is comparable to the press-hardening process well known for steels, but also includes a subsequent short-time annealing step.
To gain a fundamental understanding, short-time heat treatments were applied to Ti-6Al-4V sheet metal to produce different STQ (solution treated water quenched) and STA (solution treated annealed) states in this work. The effects of a) solution treatment temperature (below Tβ) and time followed by water quenching and b) the annealing temperature and time on microstructure and mechanical properties were focused on.
By the systematic variation of applied STQ and STA processing parameters, dominating effects on the microstructure and consequently on the quasi-static as well as cyclic properties were evaluated. The results reveal a high potential for future technical applications.
