Microstructure and Texture Characterstics of a Near-Alpha Titanium Alloy Tube

Article Preview

Abstract:

A near-alpha type titanium alloy Ti-4Al-1.5Mn tube was analyzed after extrusion deformation and annealing treatment. Electron backscattered diffraction is employed to explore the Microstructure and texture characteristic of the recrystallization alloy. The alloy is consisted of equiaxed α grains and fine β phase with {1 0-1 2} twins .It was found that the (10-10) fiber texture along the extrusion direction was the dominate texture in this alloy and the volume fraction was 40.7%.
