This proposal is aimed at investigating the crystallographic texture evolution that occurs during hot forging of two-phase alpha/beta titanium alloy Ti-64, widely used in critical gas-turbine components. Understanding the relationship between high-temperature deformation and microstructural evolution is of significant academic and commercial interest, and allows manufacturers to produce reliable components of known strength and material properties. The development of texture during hot forming of Ti-64, and the preferential selection of possible crystallographic variants during alpha/beta phase transformation, is particularly poorly understood at present. Measurements are proposed to determine the alpha- and beta-phase textures in samples during thermal cycling into the alpha + beta phase stability field, and of the alpha-phase room-temperature texture both before and after deformation.
