摘要
测定了五种Si-Mn—Mo系贝氏体钢的CCT曲线,在低Mo(<0.25%)的情形下该钢种的高温转变区大幅度右移,且贝氏体转变线在空冷冷速范围内具有扁平的特点在该钢种中,Si使贝氏体转变区右移。
CCT-diagrams of Si-Mn-Mo system bainitic steel have been determined.With Mo 0.25%, the high-temperature transformation of the steel shifts large to the right,and the bainitic transformation becomes a 'flat topped C-curve' at cooling rate in widerange. Si in the steel may cause a shift of the bainitic transformation region towards the right,and of the pro-eutectoid ferritic transformation region towards the left. Mn may delay thehigh temperature transformation more violently than the bainitic transformation.
