Abstract
In order to obtain high-quality pieces in advanced metallic alloys after hot die forging, a measurement methodology based on the association of infrared thermography with thermal inverse modelizations has been developed. It is based upon the maximum entropy principle. This report presents the method as well as numerical tests for the one-dimensional case. The two-dimensional case and results using some experimental data are also presented in both cases, where the noise influence is shown.
