text: "The phase and TTT diagrams of the Ti-6Al-4V system allow the development
of a new forming process for a more energy- and materialefficient production of
sheet metal parts. This new “TISTRAQ” process is composed of two steps. In terms
of process technology, the first step is comparable to a direct press-hardening
process already well known for steels. In this step, the Ti-6Al-4V sheet material
is resistively heated to a temperature below β-transus Tβ and, after a very short
holding time, simultaneously formed and quenched by use of water cooled tools.
Thereby, the β phase undergoes a martensitic transformation. The second step is
a subsequent short-time annealing, which leads to a hardening of the material.
In this work, a new test rig using resistive heating technique was used in order
to produce\r\ndifferent solution treated and tool quenched (STQ) and subsequently
annealed (STA) states. In this paper, the effects of heating rate, solution treatment
temperature and holding time on microstructure and mechanical properties are addressed.
For the characterisation, tensile testing and scanning electron microscopy were
used. By the systematic variation of applied processing parameters, dominating
effects on microstructure and mechanical properties were evaluated. For example,
the solution treatment temperature was found to have a significant effect on microstructural
features and characteristic strength and strain values. The obtained results reveal
a high potential for future technical applications."
