| Abstract: | The working-hardening behaviour of TRIP-assisted steels during plastic deformation was investigated by tensile test. Meanwhile, the volume fraction of retained austenite and the carbon content were measured by X-ray diffraction patterns. The results indicate that the falling rate of working-hardening exponent (n) has corresponding to the total elongation. Furthermore, the volume fraction and carbon content of retained austenite have momentous effects on falling rote of working-hardening exponent. |
