Unconventional Thermomechanical Treatment Of Advanced High Strength Low-Alloyed Steel
Original language description
Modern advanced high strength steels processed in unconventional ways of heat or thermomechanical treatment can reach substantially better properties compared to conventional treatments. This paper presents new possibilities of thermomechanical treatmentfor the 42SiCr steel. Through the conventional treatment very high strength can be reached, but the 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 the yield strength to 2000 MPa with ductility over 10%. For this purpose, the Q-P process (quenching and partitioning process) was modified and optimized in several steps. The stability of retained austenite was determined by means of neutron diffraction under cold deformation. The influence of the technological process parameters on the structure development was documented via metallography and the resulting mechanical properties were measured by means of tensile test.
