A Study of the Connection Mechanism of Cast-In High Chromium Cast Iron - Carbon Cast Steel by Cast-In Process

摘要

The connection mechanism of high chromium cast iron--carbon cast steel by cast-in process was studied by analyzing the microstructure and the alloying component in the transition zone with scanning electron microscope observation. The experiment results show that sordite pcarlite and ferrite constitute microstructure of transition zone and the connection of metallurgy is formed because of the diffusion reaction, interface reaction and formation of the new compound phase during the cast-in process.
