During the heat treatment and the welding of steel components, the interactions between the thermal and phase transformation strains result in cyclic loading of the component, which often results in plastic deformation. Although this has long been a well-known fact, the cyclic hardening behavior of supercooled austenite was not investigated up to now. In this study, tension–compression tests were...
Phase transformations in steel under stress lead to transformation-induced plasticity (TRIP), and the phase transformations are influenced, too (“Stress-dependent transformation behaviour”=SDTB). These important phenomena are currently intensively investigated. Usually one performs tension and compression tests with small specimen undergoing phase transformation in special devices like dilatometer...
