Evidence for Solute Drag during Recrystallization of Aluminum Alloys
Evidence of both solute drag as well as differences in migration mechanisms of certain boundary types has been found for an Al-Zr alloy. In-situ Transmission Electron Microscopy (TEM) annealing experiments coupled with Scanning Transmission Electron Microscopy (STEM) showed a stark contrast between Zr segregation at small and large scales. Specifically, Zr was found to segregate to, as well as ...
متن کاملSolute trapping and solute drag in a phase-field model of rapid solidification
During rapid solidification, solute may be incorporated into the solid phase at a concentration significantly different from that predicted by equilibrium thermodynamics. This process, known as solute trapping, leads to a progressive reduction in the concentration change across the interface as the solidification rate increases. Theoretical treatments of rapid solidification using traditional s...
متن کاملAutomaton Model of Precipitation / Dissolution Coupled with Solute Transport
Precipitation/dissolution reactions coupled with solute transport are modelled as a cellular automaton in which solute molecules perform a random walk on a regular lattice and react according to a local probabilistic rule. Stationary solid particles dissolve with a certain probability and, provided solid is already present or the solution is saturated, solute particles have a probability to pre...

در هر برنامه آموزشی، مهم ترین فاکتور موثر بر موفقیت دانش آموزان کتاب درسی است (مک دونو و شاو 2003). در حقیقت ، کتاب قلب آموزش زبان انگلیسی است( شلدن 1988). به دلیل اهمیت والای کتاب به عنوان عنصر ضروری کلاس های آموزش زبان ، کتب باید به دقت ارزیابی و انتخاب شده تا از هرگونه تاثیر منفی بر دانش آموزان جلوگیری شود( لیتز). این تحقیق با طراحی پرسش نامه ارزیابی کتاب که فرصت ارزیابی معتبر را به اساتید د...
15 صفحه اولMicroscopic treatment of solute trapping and drag.
The long wavelength limit of a recent microscopic phase-field crystal (PFC) theory of a binary alloy mixture is used to derive an analytical approximation for the segregation coefficient as a function of the interface velocity, and relate it to the two-point correlation function of the liquid and the thermodynamic properties of solid and liquid phases. Our results offer the first analytical der...
