Özet

Material parameters affecting the material structures can be used for modeling the deformation behaviour of super alloys. Thermo-mechanical processes are applied to P/M super alloys for consolidation. Stress-strain relationship can be established by the factors such as strain, strain rate, grain size, temperature and structural parameters. A new deformation model is suggested in this work by means of searching the compatibility of experimental results and analytical studies. In this study, P/M Rene 95 super- alloy was used as experimental material and micro-thermo-mechanical behaviors were investigated.
