Texture Evaluation of Titanium Aerospace Alloy Ti 834 Using Hot Axisymmetric Compression Tests

Article Preview

The effect of hot working strain on texture evolution in the near-α titanium alloy Ti 834 has been investigated using hot axisymmetric compression testing and EBSD. Testing was undertaken sub β transus with 22% α, which upon cooling produced a bimodal microstructure of primary α in a matrix of transformed β. Two distinct deformation induced texture components were identified: i) transverse [(0001)||compression direction] and ii) off-basal [(0001) »^ compression direction]. Orientation image mapping was then used to identify the microstructure associated with each texture component. The transverse texture is associated with the transformed β and the offbasal component is the deformation texture of the primary α.
