Microstructure and Property of High Carbonic-Chromium Cast Steel with Different Hot Deformation Ratio

摘要

The microstructure and properties of high carbonic-chromium cast steel subjected to different hot deformation ratios were studied. The experimental results show that the microstructure and properties of high carbonic-chromium cast steel are obviously improved after hot deformation, and the best mechanical properties of the cast steel can be obtained under hot deformation ratio of 40 percent - 50 percent, which leads to the morphology change of eutectic carbide and the precipitation of granular carbides.
