Abstract：By studying the changes in the influence of high-temperature carbothermal reduction and nitriding processes of vanadium oxides on product quality， the production technology of high nitrogen vanadium based multi-element alloys is comprehensively optimized. The effects of reaction time， gas influencing factors， temperature control， and other factors on product N/V， product pellet adhesion， and morphology were studied through expanded experiments to determine the optimal process parameters for the preparation of vanadium based multicomponent alloys.
