Microstructure and Mechanical Properties of 0.15C-1.5Mn-0.3Si Steel Treated by Quenching and Partitioning Process

摘要：

　　In this paper, the microstructure and mechanical properties of 0.15C-1.5Mn-0.3Si steels after quenching and partitioning (Q&P) process was studied.The microstructure of experimental steels was characterized by optical microscope (OM), scan electron microscope (SEM), transmission electron microscope (TEM) and X-ray diffraction (XRD), and mechanical properties were performed through uni-axial tensile tests.The microstructure evolution during Q&P process was also discussed together with mechanical properties.The investigated steels show excellent strength and ductility product of 10.76GPa% with retained austenite content of 11.08%.The microstructure mainly consists of lath martensite and retained austenite at room temperature, which promotes persistent work hardening during deformation.
