Precipitation kinetics in N18 P/M superalloy : experimental study and numerical modelling
Heat treatments of aeronautical turbine disks produced by powder metallurgy include y' solutionning, quenching and subsequent annealing. In the present work, the intragranular y' precipitation kinetics during the quench has been followed by dilatometry and transmission electron microscopy. The precipitation steps are studied on specimens "hyperquenched" from selected temperatures during a simul...
متن کاملThe Kinetics of Methanation on Nickel Catalysts
An empirical rate equation was obtained for the methanation kinetics catalyzed by MCR-2X, a commercial catalyst prepared by Haldor-Topsoe. The studies were carried out in a fixed-bed reactor under differential conditions, and in a gradientless recycle reactor (Berry) over a range of total pressures, reactant concentractions (H2/CO ratios), and temperatures. The kinetics of methanation were foun...

چکیده ارتباط در کلاس به عوامل زیادی از جمله معلمان، دانش آموزان، برنامه های درسی و از همه مهم تر، مواد آموزشی وابسته است. در تدریس ارتباطی زبان که تاکید زیادی بر توانش ارتباطی دارد، کتاب درسی به عنوان عامل موثر بر پویایی کلاس محسوب میگردد که درس ها را از طریق فراهم آوردن متن ارتباط کلاسی و هم چنین نوع تمرین زبانی که دانش آموزان در طول فعالیت های کلاسی به آن مشغول اند، کنترل می کند. این حقیقت ک...

Modelling plastic deformation in a single-crystal nickel-based superalloy using discrete dislocation dynamics
Background: Nickel-based superalloys are usually exposed to high static or cyclic loads in non-ambient environment, so a reliable prediction of their mechanical properties, especially plastic deformation, at elevated temperature is essential for improved damage-tolerance assessment of components. Methods: In this paper, plastic deformation in a single-crystal nickel-based superalloy CMSX4 at el...
