| 摘 要： | 采用电子背散射衍射(EBSD)技术对Zr-Nb、Zr-Sn-Nb两类锆合金的终轧退火板材组织、织构进行了研究,并对再结晶晶粒的取向差进行了表征。结果表明,两类锆合金经终轧退火后都得到了均匀细小的再结晶组织,多数晶粒尺寸在2～5μm之间;两种合金中形成的第二相差别很大,Zr-Sn-Nb合金中第二相均匀弥散,而Zr-Nb合金中第二相则存在两种形态;两种合金退火后织构均为基面平行于轧面的取向织构,并向TD方向偏转一定角度,且多数晶粒的1210∥RD方向。

| Abstract: | The evolution of microstructure and texture after final annealing treatment of two kinds of zirconium-based alloys with different composition (Zr-Nb, Zr-Sn-Nb) was investigated by electron backscatter diffraction (EBSD). The misorientation of the recrystallized grains was characterized. The results show that the grains of the alloys after final annealing treatment are uniform and equiaxed, and most of the grain sizes range from 2 to 5 μm; the second phase particles (SPPs) are very different for the two kinds of alloys. The SPPs disperse evenly in Zr-Sn-Nb, while in the Zr-Nb, there are two kinds of SPPs. The main texture of the alloys after final annealing is the basal texture, and the maximum is spread out towards the transverse direction. And the < > directions are parallel to the rolling direction. |
