Abstract

Both parameters, microstructure and texture, are studied on several samples for different processes. The same route, thermomechanical treatment (forging or rolling) followed by solutioning and ageing is carried out with various temperature and deformation amount on an identical titanium alloy CORONA 5.According to three temperature fields: low (α+β), β and high (α+β) three important microstructures are obtained: equiaxed, acicular and bimodal.All measured textures present two components which vary with deformation mode and temperature of both forging and solutioning.
