Physical simulation tests of the rapid tempering treatment on press hardened boron steel 37MnB4

Results of physical simulation tests of the thermal cycle with a heating rate of 250 K/s and hardness tests on the specimen subjected to this thermal cycle. Hardness tests were conducted along the longitudinal axis of the specimen, starting from the central point where the control thermocouple was welded.
