Abstract

In order to investigate TRIP (transformation induced plasticity) effect in different deformation style, a room temperature creep test under the constant load was conducted by using a TRIP-aided multi-microstructure steel. As a result, the volume fraction of deformation-induced martensite in the constant load creep test was larger than that in the tensile test. In situ neutron diffraction experiments during the constant load creep test were performed to discuss its reason. It is found from the in situ neutron diffraction experiments during the constant load creep tests that the phase strain of the austenite phase in the creep tests was larger than that in the tensile tests at the same applied stress.
