Crossover scaling of wavelength selection in directional solidification of binary alloys.
We simulate cellular and dendritic growth in directional solidification in dilute binary alloys using a phase-field model solved with adaptive-mesh refinement. The spacing of primary branches is examined for a wide range of thermal gradients and alloy compositions and is found to undergo a maximum as a function of pulling velocity, in agreement with experimental observations. We demonstrate tha...
متن کاملSolutal convection and morphological instability in directional solidification of binary alloys
2014 We study the effect of the coupling between front deformation and solutal convection on the position of the bifurcation from the planar quiescent state of a dilute binary alloy submitted to directional solidification. We set up a perturbation treatment of the coupling between the « bare » (Mullins-Sekerka and solutal convective) bifurcations. We show that the shift of the Mullins-Sekerka b...
متن کاملThe Adjoint Method for an Inverse Design Problem in the Directional Solidification of Binary Alloys
This paper presents a systematic procedure based on the adjoint method for solving a class of inverse directional alloy solidification design problems in which a desired growth velocity v f is achieved under stable growth conditions. To the best of our knowledge, this is the first time that a continuum adjoint formulation is proposed for the solution of an inverse problem with simultaneous heat...
متن کاملMathematical and Physical Modelling of Directional Solidification of Aerospace Alloys
Defect formation in aerospace components is studied, particularly in regions of directionally solidified casting with stepwise increase in cross-section, which is a typical geometric configuration for such components as turbine blades. Given the fact that the geometry of a casting is directly related to probability of defect formation, special attention was paid to grain defects in regions of c...
