Based on the tensile results, the product of strength and elongation of the Fe-0.42C-1.46Mn-1.58Si-0.028Nb specimen treated by Q-P-T, is up to 31627 MPa?% with elongation 20.3\%, which not only is higher than the specimen treated by Q-T process, but also meets the mechanical properties predicted of next generation advanced high strength steel. Microstructural analysis indicates the differences in Q-T and Q-P-T process lie on the amount of retained austenite and its size distribution as well as the size range of lath martensite. The former results in the low amount (<3%) of thin film-like austenite in addition to nonuniform martensite size, while the later results in the high amount of thick flake-like austenite accompanying uniform martensite size. Therefore, the higher barrier for micro-crack propagation and the better plastic deformation ability of advanced high strength steel (AHSS) can be obtained by Q-P-T treatment.
