Journal ArticleDOI
Strain rate dependent microstructural evolution during hot deformation of a hot isostatically processed nickel base superalloy
TL;DR: In this article, the role of strain rate on the microstructural evolution during hot deformation of a hot isostatically processed nickel base superalloy was analyzed using EBSD analysis.
Journal ArticleDOI
Effect of oxygen content of powder on microstructure and mechanical properties of hot isostatically pressed superalloy Inconel 718
TL;DR: In this paper, the authors show that the formation of deleterious phases such as prior particle boundaries (PPBs) occur more predominantly in the HIPed material produced from the powder with high oxygen content.
Journal ArticleDOI
Hot consolidation and mechanical properties of nanocrystalline equiatomic AlFeTiCrZnCu high entropy alloy after mechanical alloying
TL;DR: In this article, the consolidation behavior and mechanical properties of nanocrystalline equiatomic AlFeTiCrZnCu high entropy alloy after mechanical alloying were investigated by cold pressing with conventional sintering, vacuum hot pressing and hot isostatic pressing techniques.
Journal ArticleDOI
Influence of modified processing on structure and properties of hot isostatically pressed superalloy Inconel 718
TL;DR: In this article, the HIPed superalloy Inconel 718 powder was consolidated by hot isostatic pressing (HIPing) at 1200°C under 120 MPa pressure for 3h.
Journal ArticleDOI
Work hardening characteristics and microstructural evolution during hot deformation of a nickel superalloy at moderate strain rates
TL;DR: In this article, the effect of deformation temperature on the work hardening behavior of hot isostatically processed (HIPed) experimental nickel superalloy was investigated by carrying out isothermal constant true strain rate compression experiments over wide temperature ranges (1000°C, 1050 °C, 1100 °C and 1150 °C).
