【摘要】：对Ti-1300合金在固溶处理过程中晶粒的长大行为进行系统研究。结果表明:当固溶温度低于β转变温度时,未溶解的α相使得晶粒长大缓慢;在高于β转变温度固溶处理时,晶粒随着温度升高而快速增大。晶粒长大动力表明:在840~950℃固溶处理时,β晶粒的长大规律可用D=1.13×1010 exp(-2.1×104/T)描述,且晶界迁移的表观激活能为Q=350 k J/mol。当固溶温度为840、870和900℃时,晶粒长大指数随固溶温度升高而增加,分别为0.31、0.55、0.56。
[Abstract]:The grain growth behavior of Ti - 1300 alloy during the solution treatment was systematically studied . The results showed that when the solution temperature was lower than the 尾 - transition temperature , the grain grew slowly . The grain growth kinetics increased with the increase of temperature when the solution was treated at 840 ~ 950 鈩，
