Phase-field Modeling of Eutectic Solidification: From Oscillations to Invasion
نویسنده
چکیده
We develop a phase-field model of eutectic growth that uses three phase fields, admits strictly binary interfaces as stable solutions, and has a smooth free energy functional. We use this model to simulate oscillatory limit cycles in two-dimensional lamellar growth, and find a continuous evolution from lowamplitude oscillations to successive invasions of one solid phase by the other when the lamellar spacing is varied.

Computer Simulation of Equidxed Eutectic Solidifiction of Metals
In the present work, the solidification process was simulated in both macroscopic and microscopic scales. Two-dimensional heat transfer equation for conduction was applied for macroscopic modeling using enthalpy formulation and finite element method. In order to decrease execution time and/or memory capacity in finite analysis, skyline mathematical technique was adapted. The microenthalpy metho...
متن کاملPhase-Field Models for Eutectic Solidification
This article discusses two methods for modeling eutectic solidifi cation using the phase-field approach. First, a multi-phase-fi eld model is used to study the three-dimensional morphological evolution of binary eutectics. Performing the calculations in three dimensions allows observation of both lamellar and rod-like structures as well as transient phenomena such as lamellar fault motion, rod-...
متن کاملLiquation and re-solidification in thermo-mechanically affected zone during friction stir spot welding of AZ91 alloy
The present research aims to study the liquation and re-solidification of liquid during friction stir spot welding of AZ91 alloy. Although friction stir spot welding is a solid-state process, the presence of Mg17Al12 intermetallic compounds results in liquation during the welding process. In this study, friction stir spot welding was performed with a tool rotational speed of 2500 rev/min and a ...

متن کاملDirectional solidification of metal-gas eutectic and fabrication of regular porous metals
Directional solidification of metal-gas eutectic (Gasar) is a novel process for making regular porous metals. This process is based on a solid-gas eutectic reaction involving a gaseous medium and a metal or a ceramic phase, and allows an easy control of the porosity, such as its pore size, pore orientation and morphology in a wide range by properly adjusting its melting and solidification condi...
