研究了TB8钛合金冷轧板材在不同热处理温度和不同保温时间下的晶粒长大行为。结果表明： TB8钛合金冷轧板材在820～880℃的温度范围内不存在晶粒急剧粗化的现象，可以在此区间内的温度下对其进行热处理，保温时间根据温度的不同可在30～120 min范围内选择。此外，借助Beck方程和Arrhenius方程分别计算得到该合金的晶粒生长指数（n）为0.25～0.35，β晶粒长大激活能（Q）为273.23 kJ／mol。

The grain growth behavior of TB8 titanium alloy plate was investigated under different heating temperature and holding time.The results show that the cold-rolled plate of TB8 titanium alloy can be heat treated in the range of 820 ℃ to 880 ℃.The grain rapid coarsening phenomenon does not exist in the above temperature range, and the holding time can be chosen in the range of 30 min to 120 min with different temperatures.Grain growth exponent (0.25~0.35) and grain growth activation (273.23 kJ/mol) are also calculated by Beck and Arrhenius equations.
