Fabrication of High Chromium Cast Iron/Hadfield Steel Composite Materials by the Hot Rolling Process

Key Points

The composite materials exhibited no defects post-hot-rolling, indicating successful bonding between both metals.
The HCCI layer had a higher green area, suggesting elevated strain energy and dislocation density compared to Hadfield steel.
The bonding process involved physical contact, physico-chemical bonding, and mutual diffusion stages.
Analysis of the composite's microstructure confirmed effective fusion without interface cracks or unbonded areas.

Abstract

Bimetal composite blanks were successfully prepared from high chromium cast iron (HCCI) and Hadfield steel by the hot-rolling process. The macrostructure and microstructure of the composite were investigated. After hot-rolling formation, the hard HCCI layers were fractured and embedded in ductile Hadfield steel, forming a three-dimensional composite structure. The two metals were fused and no defects such as interface cracks or unbonded areas were found. A metallurgical bonding between Hadfield steel and HCCI was revealed. The kernel average misorientation (KAM) value of the Hadfield steel layer was low, while the HCCI layer showed a larger green area. It indicated that the HCCI layer had high strain energy and high dislocation density. The bonding process of two metals includes three stages: physical contact, physico-chemical bonding and mutual diffusion.
