Hot forging behavior of nickel based superalloys under elevated temperatures
چکیده انگلیسی

Thermomechanical behaviors of superalloys at high temperatures and constant strain rates related dynamic microstructural changes are studied in this article by means of the commentaries of thermomechanic graphs and microdublex changes. Thermomechanic and microdynamic deformation characteristics based on test data are presented by a methodology for superalloys which are consolidated by hot isostatic pressure (HIP) operation. It is assumed that true stress which is caused deformation, changes depending on thermomechanical behaviors such as; strain, strain rate, absolute temperature, activation energy, diffusion mechanism, grain size, microdynamic behaviors and structural parameters of the material. In this study, a detailed investigation of thermomechanical and microdynamical behaviors of powder metallurgy (PM) Rene 95 is carried on by the attribution of experimental data.
