摘　　要：对锆合金Zr-Sn-Nb进行预变形和时效处理,研究了锆合金的再结晶行为和第二相粒子的析出规律。结果表明,预变形既能够抑制第二相粒子的异常长大或粗化,又能促进粒子均匀分布。因此,Zr-Sn-Nb合金的显微组织经预变形处理后得到明显改善,有利于提高其耐蚀性。This zirconium alloys Zr-Sn-Nb were treated by pre-deformation and aging, and the recrystallization behavior and precipitation law of second phase particles of the alloy were investigated. The results show that the pre-defonnation can both suppress abnormal growth or coarsening of the second phase particles and promote uniform distribution of particles. Accordingly, the microstructures of the alloys Zr-Sn-Nb are improved significantly by the pre-deformation treatment, which is beneficial for the enhancement of corrosion resistance of the alloy.
