Microstructure of Bi-containing zirconium alloys
文献摘要:
The effect of Bi addition(0.05 wt%-0.50 wt%)on the microstructure of zirconium alloys,including T5(Zr-0.7Sn-1.0Nb-0.3Fe-0.1Cr),S5(Zr-0.8Sn-0.35Nb-0.4Fe-0.1Cr),Zr-4(Zr-1.5Sn-0.2Fe-0.1Cr)and Zr-1Nb,was investigated by transmission electron microscopy(TEM),energy-dispersive spectroscopy(EDS)and selected area electron diffraction(SAED).Results show that with the increase in Bi content,h-Zr(Fe,Cr,Nb)2,o-Zr(Fe,Sn,Bi)2 and Zr-Fe-Cr-Nb-Sn-Bi second-phase particles(SPPs)precipitate successively in the T5+xBi and S5+xBi alloys;in the Zr-4+xBi alloys,h-Zr(Fe,Cr)2,o-Zr(Fe,Sn,Bi)2,Zr-Fe-Cr-Sn-Bi and Zr-Fe-Cr-Bi SPPs are detected successively.While as for Zr-1Nb+xBi alloys,Bi-free SPPs appear.The addition of Bi promotes the precipitation of SPPs with Sn in the alloys.The con-centration of Bi dissolved in α-Zr matrix increases with the decrease in Sn content in the alloys.Adding reasonable Bi has little influence on the solid solution content of Nb in α-Zr matrix.
