Abstract: Advances in the scientific understanding of porosity development in aluminum alloys have led to the evolution of a number of descriptive models over the past four decades, ranging from analytic solutions to highly complex simulations of evolving porosity and microstructure with stochastic nucleation and growth. In this review, published models are categorized according to their approach and include analytic solutions, criteria functions, computational models using Darcy's law, gas diffusion models and continuum-stochastic models. The benefits, limitations and effectiveness of each type of model are considered. The most productive path for the future development of advanced models is proposed.
