A mechanism of high-temperature plasticity has been studied in terms of stress exponent and activation energy for deformation. A Ti3Al-based intermetallic was processed by hot-rolling in the two-phase field to accomplish a fine-grained microstructure. Compression stress-strain tests were conducted in the temperature interval rangin from 900 to 1050 degrees C and strain rates between 6.9 . 10(-5) and 2.7 . 10(-2) s(-1). Results indicate that viscous-drag dislocation glide and grain boundary sliding are the main mechanisms of deformation. Activation energy for deformation suggests dependency on the solute content in the beta-phase.
