The carbonide in the recarburized layer is mainly M23C6. The martensitic zone is composed of dislocationmartensite, twinning martensite, residual austenite and a little carbonide.
Effect of martensite volume fraction on deformation dislocation structure and fracture for hot rolled dual-phase steel of the same composition was studied by using SEM and TEM.
利用SEM、TEM研究了同一成分的热轧双相钢的马氏体体积分数对形变位错结构和断口组织特征的影响。

The deformation dislocation density and martensite microstructure were also analysed by TEM.
