加热温度对GCr15钢中贝氏体的碳化物形态影响的研究

Study on the Influences of Heating Temperature on the Carbide Morphology of Bainite in GCr15 Steel

研究了加热温度对ＧＣｒ１５ 钢贝氏体中碳化物形态的影响，结果表明，加热温度越高，上贝氏体的碳化物的长条越短； 下贝氏体中的碳化物越呈点状分布，且点状更加粗化。

The influences of heating temperature on the carbide morphology of bainite in GCr15 steel are studied. The results show that the higher the heating temperature is, the shorter the carbide strip of upper bainite is, and the more obvious the point shape distribution of the carbides in under bainite, the coarser the point shape.
