The influence of Hadifield Steel-bonded TiC preparation process on microstructure and properties

摘要

In the paper, we selected high manganese steel as the binder and titanium carbide as the hard phase, which could attain single austenite bonded titanium carbide after water toughening in order to combine excellent toughness of matrix with good wear resistance of TiC organically for some components that required excellent toughness and wearability. By dint of SEM, XRD etc. detection means, effects of ingredient proportion, preparation technics and heat treatment parameters on hardness, microstructure, and mechanical property were investigated; so the composition and preparation process of TiC cemented were confirmed, which was applied to grinding with large impact force.
