... with a colony-alpha microstructure. The occurrence of nonuniform grain structures (and so-called ALA, or “as large as,” grains) in cast, wrought, and powder-metallurgy superalloys is also discussed. A physics-based model to treat the topology of recrystallization and the evolution of ALA grains...

...S. F. Hassan; M. Gupta Nano- Y 2 O 3 particulates containing ductile magnesium nanocomposites were synthesized using blend-press-sinter powder metallurgy technique followed by hot extrusion. Microstructural characterization of the nanocomposite samples showed fairly uniform reinforcement...

...Gerald T. Cashman A methodology is presented for the preparation of a competing modes fatigue design curve. Examples using extruded and isothermally forged powder metallurgy René 95 are presented. Monte Carlo simulation results are given to identify sample size requirements appropriate...

...Gerald T. Cashman Elevated temperature data for powder metallurgy alloy René 95 generated in vacuum are presented to demonstrate that the life differences observed between surface and internally initiated failures are due to an environmental effect. The transition in behavior from a mode at low...
