Abstract Scope |
In this present investigation, quenching and partitioning method was applied to deformed low carbon multiphase steels. The Effect of partitioning temperature after quenching below and above Ms temperature on the microstructure and mechanical properties are investigated. The resulting multiphase microstructures are investigated by using optical microscopy, Scanning Electron microscopy and X-ray diffraction techniques. The mechanical properties are evaluated. The microstructure consists of martensite/bainite, temper- martensite and retained austenite. The tensile strength significantly increases than deformed steels but ductility decreases. The fatigue strength is increase in 300C and 350C. The quenching below Ms temperature and holding at 300C shows a good strength and ductility combination with Fatigue strength. |
