介绍了几种新锆合金４００℃，１０．３ＭＰａ静态高压釜试验结果和室温及高温（３７５℃）的拉伸试验结果，分析了新合金中合金元素Ｎｂ．Ｓｎ．Ｆｅ．Ｃｒ对抗伸强度及耐蚀性能的影响。结果表明：通过控制合金元素的含量，在经历与Ｚｒ－４相同的生产工艺条件下、可以得到强度和耐蚀性能更为优异的新铝合金。试验表明：这种新型的Ｚｒ－Ｓｎ－Ｆｅ－Ｃｒ－Ｎｂ中加入Ｎｂ量应在０．１ｗｔ％－０．３ｗｔ％之间；在含１ｗｔ％Ｎｂ的新合金中，Ｓｎ的含量不应低于０．５ｗｔ％：在新合金研制时，适当提高Ｆｅ＋Ｃｒ的含量是有益的，但Ｆｅ／Ｃｒ比不应太高。
The experimental results of several new zirconium alloys at 400 ℃ and 10.3MPa and the tensile tests at room temperature and high temperature (375 ℃) are introduced. Alloying elements Nb in the new alloy are analyzed. Sn. Fe. Effect of Cr on Tensile Strength and Corrosion Resistance. The results show that by controlling the content of alloying elements, the new aluminum alloy with better strength and corrosion resistance can be obtained under the same production process as Zr-4. The tests show that the amount of Nb added to the novel Zr-Sn-Fe-Cr-Nb should be between 0.1 wt% and 0.3 wt%; the content of Sn in the new alloy containing 1 wt% Nb should not be low At 0.5wt%: In the development of new alloys, it is beneficial to properly increase the content of Fe + Cr, but the Fe / Cr ratio should not be too high.
