Study of hot multiaxial processing of titanium alloy

An original procedure is presented to take advantage of temperature and strain gradients similar to the ones encountered in hot open-die forging of titanium alloys. The multi-axial deformation module MaxStrain of the physical simulation system “Gleeble 3500” is used to create complex deformation paths close to industrial ones. The gradients will be identified by crossing microstructure fields and finite element simulation of thermomechanical gradients, in order to understand the effect of such gradients on the material flow and on the microstructural transformations.
