| 摘 要： | 研究了电子柬熔炼工艺对Nb—W合金化学成分及力学性能的影响．结果表明：电子束熔炼次数越多，Nb—W合金的Zr含量越低，而电子束熔炼次数对W，Mo合金元素含量影响不大；经过多次电子束熔炼后的铸锭中C含量明显低于Nb—Ww—Mo烧结条和一次电子束熔炼锭中的C含量，而两次和三次电子束熔炼锭的C含量区别不大；由于ZrC对Nb—W合金的弥散强化，两次电子柬熔炼制备的棒材强度明显高于三次熔炼制备的棒材．

| Abstract: | The effect of electron-beam melting process on composition and mechanical property of Nb-W Alloy is analyzed.The results show that the more times electron-beam melting is,the less Zr content there is in the Nb-W alloy,and the times of electron-beam melting has less effect on the W,Mo content.The C content in several times electron-beam melting ingot is apparently less than that in sintered bars and one time electron-beam melting ingot,and there is not much difference of C content between two and three times electron-beam melting ingots.Meanwhile,the mechanical strength of two times electron-beam melting rod is superior to three times electron-beam melting rod,due to the dispersion strengthening of ZrC. |
