摘　　要：研究了Zr-Sn-Nb-Fe-Cr锆合金真空电子束焊接样品的拉伸和抗腐蚀性能,结果表明,焊接样品室温和375℃的拉伸性能略低于母材;焊接样品在500℃过热蒸汽中腐蚀500 h未出现疖状腐蚀现象,但腐蚀增重略大于母材;在400℃过热蒸汽中腐蚀320 d及360℃水中腐蚀520d,样品焊缝处颜色均为黑亮,未出现白色、棕色等腐蚀产物。根据实验结果拟合出了焊接样品的腐蚀增重曲线。The mechanical properties and corrosion resistance of the sample made by vacuum electron bean welding of Zr-Sn-Nb-Fe-Cr zirconium alloy were investigated. The results show mechanical properties at room temperature and 375 ℃ temperature of welding sample were lower than matrix.The nodular corrosion can not be found of welding sample corroded in superheated steam for 500 h,but the weight gain was higher than matrix.The color of welding seams was black.The weight gain curves made by test result of welding sample were given.
