【Abstract】 This paper introduces the process of producing HBR400 by V-N alloy to replace V-Fe.Practice and research showed that a lower content brought by V-N alloy can gain the same mechanical properties as compared with the process o fusing V-Fe alloy.Therefore,this process can reduce the production cost.In addition,the relationship between the mechanical properties of HBR400 and its chemical compositions were observed.更多还原
