Small amounts of titanium (ⅳ), tungsten (ⅵ), uranium (ⅵ) and thorium ions do not interfere the determination of niobium. 少量的钛(Ⅳ)、钨(Ⅵ)、铀(Ⅵ)、钍存在时,不干扰铌的测定。
The effect of substitution of titanium with tungsten on microstructure of in situ synthesized 10 % TiC / Fe ( volume fraction ) composite was investigated. 研究了原位自生10%TiC/Fe(体积分数)复合材料显微组织及W对该复合材料的影响作用。
