亚温处理中锰钢碳化物粒化机制

The Mechanism of the Carbides Graining for the Medium-Mn Cast Steels at the IHT

本文通过对大量试验结果的观察研究,分析了中锰铸钢亚温处理时碳化物转变的动力学规律,并提出了碳化物分枝粒化机制的假设,为中锰铸钢强韧化研究提供了重要的理论依据.

In this paper, with observing a great deal of experimental results, the kinetics laws of the transformatins of the carbides for the medium-Mn Steels at the intercritical heat treatment have been studied and analysed, and the hypothesis of the grained mechanism at branches of the carbides has been proposed. Our work provides an important basis for improving the toughness of the medium-Mn steels.
