Abstract
The phase diagram of WC-Cr3C2-15 mass%Ni alloy was previously studied by the authors. The present study was undertaken to describe some properties such as mechanical properties, resistances to corrosion and oxidation, etc. of two-phase WC-Cr3C2-15 mass%Ni alloy in relation to Cr3C2 and carbon contents of the alloy.
It was found that the properties of two-phase alloy varied in a regular manner according to the Cr3C2 and carbon contents. For instance, transverse-rupture strength and hardness of the alloy increased with increasing Cr3C2 (up to 2-3 mass%) and decreasing carbon contents within the phase region. The resistance to corrosion in different solutions showed a strong dependency on the binder phase compositions.
