Titanium and its alloys have increasingly become a material of choice in high performance structures due to superior corrosion resistance and high strength to weight ratio for applications ranging from deepwater offshore structures to military high-speed crafts. Highly localized features in a residual stress distribution typically imply potential benefits in some aspects of design and manufacturability evaluations if such features can be confirmed through advanced residual stress measurement techniques such as neutron diffraction. This proposed study will be focused on experimental confirmation of some of the important local residual stress features such as magnitude and the length scale under which the longitudinal stress transitions from positive to negative. Computational modelling techniques will be used to facilitate the detailed measurement planning and data interpretation.
