【摘要】 对压缩变形制备超细晶钛合金的可行性进行了初步的实验研究。结果表明， 低于７２５℃的压缩变形可以在ＴＣ１１合金中获得亚微米晶组织； 变形中α相发生再结晶， 而同时β相经历一个析出和长大的过程；变形促进了β相的析出和长大， 也改变了β析出相的形态更多还原

【Abstract】 The possibility to produce ultrafine grained titanium alloy by compressive deformation was examined tentatively. It is shown that submicron grained TC11 alloy can be obtained by compressive deformation below 725℃. During microstructure refinement, dynamic recrystallization occurs only in α phases, and β phases undergo a process of precipitation and growth. Compared with the situation of static annealing, deformation can not only enhance the precipitation and growth of β phases but also change the morphology of β precipitates.更多还原
