| Abstract: | The effects of thermal processing technology on microstructure of 0.23%C-- 0.60% Si-1.50% Mn --0.44Ceq intermediate and low carbon Si-Mn steel were researched. The precipitation conditions of intragran ular eutectoid ferrite were verified. The stress-strain curves and CCT curves were obtained. The effects of de formation temperature on softening rate, dynamic recrystallization rate, transformation point, pearlite spacing, ferrite grain size and dislocation density of the sample were analyzed. |
| Keywords: | thermal processing CCT DRX intragranular ferrite pearlite spacing dislocation density |
