Abstract : In this final report are discussed the results obtained in a two year investigation by Crystal Growth and materials Testing Associates of the deformation mechanisms of thermostructural materials. This report is divided into three portions: 1. Some effects of the presence of particles near free surfaces; 2. Improvement of turbine blades and other components by hot isostatic pressing; 3. Thermal and thermo-mechanical fatigue of superalloy Rene 80 coated with CoCrA1Y. Keywords: Cobalt, Chromium, Aluminum alloys.
