Evolution of recorded microstructures in minerals during cooling of Zarrin intrusion, evidence for dynamic deformation
The Zarrin granitoids is located in the west of Yazd block, Central Iran. Zarrin granitoids exhibit mylonitic rocks ranging from protomylonitic to mylontic. In Zarrin granitoids examples of sub-magmatic, microstructures are represented by chessboard patterns in quartz and sub-magmatic fractures in plagioclase, indicating deformation at high-temperature conditions (T > 650º C) and the presence o...
متن کاملAsymmetric oscillations during phase separation under continuous cooling: A simple model.
We investigate the phase separation of binary mixtures under continuous cooling using the Cahn-Hilliard equation including the effect of gravity. In our simple model, sedimentation is accounted for by instantaneously "removing" droplets from the supersaturated mixture into the coexisting phase once the droplets have reached a defined maximum size. Our model predicts an oscillatory variation of ...
متن کاملPhase separation under ultraslow cooling: Onset of nucleation.
We discuss the interplay between a slow continuous drift of temperature, which induces continuous phase separation, and the nonlinear diffusion term in the phi(4)-model for phase separation of a binary mixture. This leads to a bound for the stability of diffusive demixing. It is demonstrated that the same findings apply in other models, except for slight modifications of the bound. In practice ...
متن کاملCellular automaton simulation of microstructure evolution during austenite decomposition under continuous cooling conditions
A two-dimensional diffusion based model is developed to describe transformation of austenite into ferrite and pearlite under continuous cooling conditions. The nucleation of ferrite is assumed to occur over grain boundaries and the nucleation of pearlite is assumed to be taking place all over the grain and at growing ferrite–austenite interfaces, when the composition and temperature conditions ...

در این پایان نامه رنگ آمیزی دینامیکی یک گراف را بیان و مطالعه می کنیم. یک –kرنگ آمیزی سره ی رأسی گراف g را رنگ آمیزی دینامیکی می نامند اگر در همسایه های هر رأس v?v(g) با درجه ی حداقل 2، حداقل 2 رنگ متفاوت ظاهر شوند. کوچکترین عدد صحیح k، به طوری که g دارای –kرنگ آمیزی دینامیکی باشد را عدد رنگی دینامیکی g می نامند و آنرا با نماد ?_2 (g) نمایش می دهند. مونت گمری حدس زده است که تمام گراف های منتظم ...
