Characterization of Ti and Ni Alloys for Hot Forging:Setting-up of an Experimental Procedure

There is a growing interest in the application of Titanium and Nickel alloys forged components in the aerospace and Hi-Tech industry. Hot forging of these alloys requires a precise definition and control of operating parameters, such as forging temperature, punch speed and lubricant. A procedure is presented to obtain true stress true strain curves for Ti and Ni alloys at hot forging conditions, that is especially designed to guarantee homogeneity at deformation and temperature in the specimen during the overall compression test.
