Diffusion behaviour in high-chromium cast iron/low-carbon steel bimetals

In the present study, three high-chromium cast irons (HCCIs) with different Cr-content were bonded to low-carbon steel (LCS) and the effects of the Cr-content on the bonding and atomic diffusion behaviour between the HCCIs and the LCS investigated. The results show that the HCCIs and LCS showed good metallurgical bond with intact interfaces, without any micro-defects. The volume fraction of carbides in HCCIs increased with an increase of...
