The deformation behaviour of a model Ti-Mn alloy is described in terms of the deformation response of the component phases. Room temperature compression tests were conducted at different strain rates. A high logging rate thermocouple was employed to measure the real sample temperature during the experiments in order to study the effect of deformation heating. As expected, the 0. 2% proof stress,sample temperature rise and strain rate sensitivity increased with the beta phase volume fraction. The alpha+beta titanium alloy was treated as a composite material and the rule of mixtures (ROM) was employed to describe the flow behaviour based on constitutive modelling of the component phases. A model implemented under iso-strain and iso-work assumptions gave the best prediction.
