FABRICATION OF SUBMICRON GRAINED TITANIUM ALLOY BY COMPRESSIVE DEFORMATION

Abstract

Abstract: This paper reviews various fabrication methods of ultrafine grained materials and their limitations briefly, and examines the possibility to produce ultrafine grained titanium alloy by compressive deformation preliminarily. It has been shown that submicrongrained TC11 alloy can be obtained by compressive deformation below 725°C. 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 βprecipitates.

Key words: TC11 alloy, submicron grain, compressive deformation, superplasticity
