Abstract Effects of initial martensite on the microstructure and mechanical properties of quenching and partitioning (Q&P)low alloy steel were investigated. The microstructure characterization and austenite fraction measurement were carried out in scanning electron microscopy and X-rays diffraction. It was found that with increasing fraction of initial martensite， the size and amount of fresh martensite decreased gradually， and the volume fraction of retained austenite increased firstly and then decreased， the maximum volume fraction of retained austenite of 16.92% was obtained when the initial martensite fraction was 40%. The higher ductility and the product of the tensile strength to total elongation could be obtained with the initial martensite fraction ranging from 30%-70%， the martensite matrix of steel guaranteed?the high strength， and the TRIP effect of retained austenite during deformation improved the ductility of steel.
