  text: Within the current energy and environmental crisis, new material- and energy-saving
    processes are needed. For this reason, this study focuses on the development of
    a new forming technology for Ti-6Al-4V sheet metal. It is based on combination
    of solution treatment by resistive heating with rapid tool-based quenching and
    subsequent annealing. This new “TISTRAQ” process is comparable with press-hardening
    already known for steels and hot die quenching known for aluminium alloys. One
    of the main influencing factors for this process is the heat transfer coefficient
    (HTC). It is an important driver for adjustment of basic parameters, as selection
    of tool material or the forming speed but also plays an important role while elaborating
    temperature distribution in the numerical model. Therefore, a new and unique test
    rig was developed to determine the HTC and to perform tool-based heat treatment
    at specimen level under laboratory conditions. The test rig was used to investigate
    the influence of the titanium-tool-lubricant system on HTC and cooling rate. Further
    the effect of heat treatment in the test rig and tool-based quenching on microstructure
    and mechanical properties was studied. To improve the prediction of the temperature
    distribution of the titanium during cooling, the HTC was integrated into the numerical
    process simulation
