在 WC- 10 % Ni合金中添加适量 VC会使合金在两相区高碳的情况下 ,从有磁性转变为无磁性。本文探讨了 VC使 WC- 10 % Ni硬质合金磁性转变的机理 The addition of the proper amount of VC in WC-10% Ni alloy makes the alloy change from magnetic to non-magnetic under the condition of high carbon in two-phase region. This paper explores the mechanism of VC in the magnetic transformation of WC-10% Ni cemented carbide
