Unconventional Thermomechanical Treatment of Advanced High Strength Low-Alloy Steel
Original language description
Modern advanced high strength steels processed using unconventional heat or thermomechanical treatments can attain substantially better properties when compared to conventional treatments. This paper presents new possibilities of thermomechanical treatment for 42SiCr steel. Very high strength can be reached using conventional treatments, but ductility drops down to lower values. The aim of this experiment was to design and test an unconventional thermomechanical treatment procedure in order to reach a yield strength of up to 2000 MPa with ductility over 10%. For this purpose, the new kind of heat treatment the Q-P process (Quenching - Partitioning) was modified and optimized in several steps. The stability of retained austenite was determined by meansof neutron diffraction under cold deformation. The influence of the technological process parameters on structure development was documented via metallography and the resulting mechanical properties were measured by means of tensile test.
