The research of improving the smelting quality of D2 steel(steel) The alloy elements of D2 steel e.g., Cr, Mo, V will form a large number of carbides during the solidification and eutectoid transition. Tough the fishbone eutectic carbide can be broken during rolling or forging etc thermal deformation process, but under the influence of rolling or forging direction, the distribution of ca ...

The alloy elements of D2 steel e.g., Cr, Mo, V will form a large number of carbides during the solidification and eutectoid transition. Tough the fishbone eutectic carbide can be broken during rolling or forging etc thermal deformation process, but under the influence of rolling or forging direction, the distribution of carbides in steel is still uneven.
