摘要(Abstract)：

首先对冷轧态Ti-49Zr-21Nb-1.0Sn(TZNS1.0)合金分别在600、650、700、750、800和850℃进行再结晶退火处理10、20、30、60、90和120 min,随后采用光学显微镜(OM)和电子背散射衍射(EBSD)技术分析了热处理后合金的组织演变，计算了合金的再结晶激活能，建立了其再结晶动力学模型。结果表明：随着退火温度的升高，TZNS1.0合金的再结晶形核孕育时间缩短，β晶粒经历了回复、再结晶形核和长大阶段。随着退火时间的增加，合金的晶粒尺寸增大，但长大速度逐渐减小。TZNS1.0合金在750℃再结晶退火后，仅少数区域发生再结晶，大部分区域仍为变形组织，并存在许多小角度晶界、高密度位错和轧制织构。在800℃退火后，再结晶区域呈现大角度晶界，轧制织构和高密度位错被消除。退火温度进一步升高到850℃时，再结晶过程全部完成，合金晶粒明显长大。TZNS1.0合金的再结晶激活能为67.45 kJ/mol, 850℃退火处理时，合金的再结晶动力学方程为x=1-e~(-0.05t~(0.9))。
