The extra vanadium exists in austenite as coarse vanadium enriched carbides or in bainite as vanadium carbide particles. 一部分钒以含钒碳化物的形式呈块状存在于奥氏体中或呈颗粒状分布在贝氏体基体中。 - 2
The results show that, typical morphologies of vanadium carbide appears in the shape of sphericity and strip, and chromium carbide appears lump and lath. 结果表明，钒碳化物为球状和条状，铬碳化物为块状和板条状。 - 3
Since the vanadium oxide is softer than vanadium carbide, it is easily reduced to fine particles in the step of mixing by means of a ball mill in raw-material preparation. 由于氧化钒 与碳化钒相比较为柔软，因此在配制原料时在采用球磨机进行混合的步骤中 容易进行微粒化。
