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

Description

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. Financed by the European Union - NextGenerationEU (National Sustainable Mobility Center CN00000023, Italian Ministry of University and Research Decree n. 1033 - 17/06/2022, Spoke 11 - Innovative Materials & Lightweighting).

Steps to reproduce

Physical simulation tests carried out on the physical simulator Gleeble®3180. The thermal cycles included a heating phase up to a temperature of 800°C, heating rate of 250 K/s, followed by rapid cooling. Hardness tests were conducted along the longitudinal axis of the specimen, starting from the central point where the control thermocouple was welded.
