The mechanical properties of the thus quenched 27SiMn steel are better than that of the thus normalized 27SiMn steel. The effect of original structure on the mechanical properties of 27SiMn steel is prominent when the zero time holding quenching temperature is lower, but it decreases with an increase of the quenching temperature.

CCT curves of low carbon Mn Si steels and development of

Abstract. CCT curves of Mn Si steels with different manganese contents or carbon contents were determined. The results show that the transformation range of bainite can be separated from that of ferrite when the manganese content approaches a certain content, and the incubation period of ferrite increases more significantly than that of bainite transformation with the increase of carbon
