Abstract

Abstract: The properties of hypoeutectic iron of HCWCI containing 25 wt. %Cr-2.5 wt. %C were investigated after destabilisation heat treatments, cooling (slow and fast cooling) to ambient temperatures, their influence on the structure and hardness was investigated using X-ray diffraction (XRD), element distribution analysis and hardness tests. The experimental results show that appropriate heat treatments contribute to a significant improvement on the mechanical properties of selected alloy of HCWCI. The results are discussed in terms of the change in austenite phase at the different destabilisation heat treatment temperatures.
