Abstract
The WC-Ni alloy containing Cr3C2 has been widely used for non-magnetic or corrosion resisting parts. However, the (WC+γ) two-phase region of WC-Ni alloy affected by the Cr3C2 addition seems not to have been studied. The present work was concerned with this subject for WC-Cr3C2-15%Ni alloy. It was found that the two-phase and the adjacent (WC+γ+Cr3C2) three-phase regions shifted markedly to the high carbon side. It was also found that the solid solubility of Cr in the binder phase varied according to the carbon content of alloy and it showed a maximum value of about 16% for the alloy containing about 5.8%C.
