High strength carbides in cast chromium alloys

When the volume fraction of carbide with high hardness in the solidification structure of Cr based alloy is 20 ~ 35% and evenly distributed in the matrix, the wear resistance of the alloy is the best. These carbides can exist as eutectic carbides or primary carbides. The morphology of...

Solidification structure of Hypereutectic cast chromium alloy

The whole contour of eutectic structure in hypereutectic chromium cast iron is very similar to that of Hypoeutectic and eutectic chromium white cast iron. The difference is that the primary phase is no longer austenite, but hexagonal primary carbide. Eutectic carbides grow continuously on primary carbides, and there is...

Classification of cast chromium alloys

The solidification structure of chromium alloys is closely related to the content of C and Cr in them. According to its different Cr content and application in different technical fields, it can be roughly divided into three categories (1) Low chromium cast iron Low chromium cast iron is defined...
