the purpose of this study was to investigate the effect of heat treatment including solution treatment and aging on the microstructure of cast nickel-based in100 superalloy including size, volume fraction and morphology of primary γ' and different kinds of carbides. for this purpose, different solution heat treatment cycles and a constant aging cycle were implemented on cast ingot samples and t...

The tribological behavior of a nickel-based single crystal superalloy treated by shot-peening has been investigated. Friction tests under three normal loads and temperatures were carried out based on the ball-on-disk configuration. results showed that coefficient friction (COF) wear rate shot-peened (SP-NBSC) at room temperature nearly 2 times 4 600 ?, respectively. However, there no significan...

in the present study, the microstructural changes of a nickel based superalloy nimonic80a during a non-isothermal deformation were studied. therefore, microstructure evolutionduring hot side pressing test was predicted with combined methods of finite element analysis andprocessing map of the material. the predicted results were validated through experimentalmicrostructural studies. the results ...
