Convection effect on solidification microstructure: dendritic arm spacing and microsegregation
نویسندگان
چکیده
Abstract Convection affect primary crystalline structure, particularly, the dendrite crystal velocity and tip radius. The present work aims on influence of convective flow spacing between neighbouring crystals within ensemble. Solidification a binary alloy is considered model stagnant boundary layer, under imposed thermal gradient which microstructure chemical microsegregation. Chemical composition in solidifying liquid solid derived from solution solute diffusion transport equation taking into account flow. results are consistent with Scheil-Brody-Flemings model, experimental data computational results.

Modelling of dendritic growth during alloy solidification under natural convection
A two-dimensional (2D) lattice Boltzmann method (LBM)-cellular automaton model is presented to investigate the dendritic growth of binary alloys in the presence of natural convection. The kinetic-based LBM is adopted to calculate the transport phenomena by the evolution of distribution functions of moving pseudo-particles. To numerically solve natural convection thermal and solute transport sim...
متن کاملModeling of Dendritic Growth in Alloy Solidification with Melt Convection
In typical solidification processes the flow of molten metal is usually regarded as an unavoidable phenomenon potentially affecting the morphology of dendritic growth. Fundamental understanding of such flow is thus important for predicting and controlling solidification microstructures. This paper presents numerical simulations on the evolution of dendritic microstructures with melt convection....
متن کاملEquiaxed Dendritic Solidification with Convection Part I. Multiscale/Multiphase Modeling
Equiaxed dendritic solidification in the presence of melt convection and solid-phase transport is investigated in a series of three articles. In part I, a multiphase model is developed to predict composition and structure evolution in an alloy solidifying with an equiaxed morphology. The model accounts for the transport phenomena occurring on the macroscopic (system) scale, as well as the grain...
متن کاملSolidification microstructure development
In the present article, evolution of microstructure during solidification, as a function of various parameters, is discussed. Macrosegregation is described as being due to insufficient diffusivity of solute in the solid. Pattern formation is discussed in the light of instabilities at the solidification growth front. An overview of the scaling relations for various microstructures is given. Meta...
