چکیده

In the last decade problem of dendritic grain structure prediction has been intensively analysed. Several approaches have been proposed including the phase field method, methods related to the Monte Carlo model, cellular automata and finite element methods as well as hybrids of above [13,6,2]. At the same time, to understand a physical background of the process, several experimental studies have been carried out [1]. Recently several approaches based on the cellular automata have been proposed. In [3] Coxe and Reiter created simple fuzzy automata that allow simulating the growth of snowflakes but without physical basis. In [12] Wang et al. proposed model, also based on cellular automata, of microstructural development and primary spacing by both branching and overgrowth mechanism. The most advanced solution has been developed by M. Rappaz and Gandin in [4,8]. In this method the processes of nucleation and growth are simultaneously considered resulting in very accurate model. In this paper we present object-oriented implementation of the abovementioned Rappaz and Gandin approach. This software has been created to extend a functionality

Modelling of Equiaxed Microstructure in Castings

The paper deals with a numerical modelling of equiaxed microstructure formation during the solidification of two-component alloys. The basic enthalpy formulation was applied to model the solidification. The equiaxed grain size was dependent on the average cooling velocity at the moment when the liquid metal reaches the liquidus temperature. The experimentally determined dependence between grain...

Macroscopic Model for Predicting Columnar to Equiaxed Transitions using Columnar Front Tracking and Average Equiaxed Growth

A macroscopic model of Columnar-to-Equiaxed Transition (CET) formation is presented. The growth of a columnar zone and an equiaxed zone are treated separately and modeled on a fixed grid. The model uses a columnar Front Tracking (FT) formulation to compute the motion of the columnar front and the solidification of the dendritic columnar mushy zone. The model for the equiaxed zone calculates the...

Grain Structure Control of Additively Manufactured Metallic Materials

Grain structure control is challenging for metal additive manufacturing (AM). Grain structure optimization requires the control of grain morphology with grain size refinement, which can improve the mechanical properties of additive manufactured components. This work summarizes methods to promote fine equiaxed grains in both the additive manufacturing process and subsequent heat treatment. Influ...

Monte-Carlo Simulation of Grain Growth in <100> Fiber Textured Material

Monte-Carlo models are becoming increasingly popular for studying the temporal and spatial aspects of grain growth during the annealing of metals. For example, both normal and abnormal grain growth have been examined for metals with fine, equiaxed microstructure. In addition, research to establish the effect of anisotropic grainboundary energy and mobility on growth behavior has been undertaken...

Equiaxed 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...

Using a Three-phase Mixed Columnar-equiaxed Solidification Model to Study Macrosegregation in Ingot Castings: Perspectives and Limitations

A three-phase model for mixed columnar-equiaxed solidification was recently developed. The most critical features, necessary for modelling the macrosegregation, were considered: the progressive growth of the columnar dendrite trunks from the ingot surface, the nucleation and growth of the equiaxed crystals including the motion of the equiaxed crystals, the thermal and solutal buoyancy flow and ...
