【摘要】 研究了锡含量对锆－锡合金力学性能和腐蚀性能的影响。结果表明：锡在０．５ｗｔ％～１．７ｗｔ％范围内，随着锡含量的增加，合金的强度增加，在４００℃蒸汽腐蚀试验中，随着合金中锡含量的减少，腐蚀增重降低并能改善合金的抗疖状腐蚀能力。更多还原

【Abstract】 he effects of Sn content on mechanical properties and corrosion resistance of Zircaloy have been studied. The results show that strength of the alloy increases with the increase of Sn content in the range of 0.5wt% ￣1.7wt% Sn. Corrosion weight gain of the alloy drops with the decrease of Sn content in autoclave test at 400℃steam and nodular corrosion resistance is also improved with the decrease of Sn content.更多还原
