引言弹性铌合金具有耐蚀性、无磁性、高温恒弹性、弹性模量低、弹性极限高和弹性滞后小等优良的综合性能。它们形成了弹性材料的新分支。1965年以来有些这方面的文献报导。我院从1974年开始研究弹性铌合金(主要是Nb-Ti系和Nb-Zr系合金)。且从1977年起我们研制的几种成分的铌合金已成功地用于各方面。但大多用于耐蚀仪表中。例如,在北京有机化工厂,用作耐120℃的醋酸及次氯酸钠腐蚀的波纹膜片材料。冲型平整,能和不锈钢焊接,
Introduction Flexible niobium alloy with corrosion resistance, non-magnetic, high temperature constant elasticity, low modulus of elasticity, high elastic limit and small elastic hysteresis excellent comprehensive performance. They form a new branch of elastic material. Some articles in this area have been reported since 1965. Since 1974, our institute has studied elastic niobium alloys (mainly Nb-Ti and Nb-Zr alloys). And from 1977 onwards we developed several components of niobium alloy has been successfully used in all aspects. But mostly used in corrosion-resistant instruments. For example, in Beijing organic chemical plant, used as a corrugated membrane material resistant to acetic acid and sodium hypochlorite corrosion of 120 ℃.
