Composite Modelling of a Two-phase Titanium Alloy
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 isostrain and iso-work assumptions gave the best prediction.
