On the High Temperature Deformation of Titanium-Aluminum Alloys.
Abstract
rientation(Direction), Strain(Mechanics), Turbine bladesA study of high temperature deformation in the titanium-aluminum binary system was undertaken to support the development of titanium alloys for use over the temperature range 900F to 1200F. Specimens containing four, five, six, eight and ten weight % aluminum were creep tested to compare single-phase material with an alloy containing a second phase, Ti3Al. The starting material is shown to have a strong texture which is related to a reduction in the difference in critical resolved shear stress between the basal and prismatic planes. Creep testing revealed that the activation energy for steady state creep is a function of stress and aluminum content over the temperature range of 900F to 1400F but was inconclusive in identifying the principal mode of deformation.
