The influence of original structure on the microstructure

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.The influence of original structure on the microstructure 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.THE INFLUENCE OF ORIGINAL STRUCTURES ON THEparameters on the mechanical properties of the steel.However,there are relatively few(er) reports of the structural inheritance of structural steels with zero time holding quenching.In this work,the microstructure and mechanical properties of the zero time holding quenched 27SiMn steel were measured,which were pretreated
