TL;DR: In this article, a comprehensive stochastic model for simulating the evolution of dendritic crystals during the solidification of binary alloys was developed, which includes time-dependent calculations for temperature distribution, solute redistribution in the liquid and solid phases, curvature, and growth anisotropy without further assumptions on the nucleation and growth of Dendrite crystals.

TL;DR: In this article, a new analytical mathematical model for solute redistribution was developed, which does not require a prescribed movement of the interface and can be used for one-dimensional (1-D) or two-dimensional or three-dimensional calculations.

TL;DR: To relax many of the assumptions used in continuum approaches, a general stochastic model has been developed that can be used not only for an accurate description of the fraction of solid evolution, and therefore accurate cooling curves, but also for simulation of microstructure formation in castings.

TL;DR: In this article, a comprehensive review of the state of the art and challenges involved in investment casting of Ti-6Al-4V (Ti-6-4) alloy to improve the quality, costs and manufacturing of Ti parts is presented.

TL;DR: In this paper, a number of models for predicting the evolution of the solidification structure are presented. But the authors focus on the dynamics of the process and do not address the simulation aspects of the model.
