| Abstract: | In order to enhance the plasticity,a certain amount of retained austenite was obtained treated by Q&P process in martensitic steel,and the combination of excellent strength and plasticity was accomplished.The microstructure and mechanical properties of the low carbon Q&P steel were investigated by scan electron microscope(SEM),transmission electron microscope(TEM),X-ray diffraction(XRD) and tensile test.The effects of partition process on retained austenite and the effect of retained austenite on elongation... |
