A lot of steels with advanced thermal and mechanical properties have been developed in the last decade. Those steels contain high amounts of alloying elements, for example manganese or aluminum for high load applications. However, the added elements imply challenges for the casting properties. One of those properties is the hot tearing tendency, the main reason for welds or rejects in steel casting. For characterizing the hot tearing tendency in steel castings a sand mold for in-situ measurements in the solidifying melt was developed. This mold is designed by solidification simulation and equipped with thermocouples and a load cell to measure the point of crack initiation. This point is characterized by the beginning force reduction at a certain temperature during solidification. The resulting data set of several steels can be combined with thermodynamic calculations in order to predict the hot tearing tendency in advance.
