Study on the design of quenching fixture in hot press forming process

In hot press forming process, the desired high strength can be obtained through quenching process after cold forming of product. The quenching process, however, accompanies undesired distortion due to the volume change during the phase transformation as well as by thermal contraction. In this study the numerical simulation with DEFORM3D-Microstructure is used to predict the deformed shape during the quenching for the quenching fixture design.
