It is, in fact, one of the most important issues in the control of microstructure 1. Grain size is a very important characteristic for evaluating the properties of the materials, especially when we need to balance different ones. Keywords: Monte Carlo simulation, grain growth, physical metallurgy, scientific visualization A very close relationship between experimental and theoretical values for the grain growth exponent (n) was observed.
WHAT IS MONTE CARLO SIMULATION SERIES
The measure of time is the Monte Carlo Step (MCS), which involves a series of trials throughout the lattice.
WHAT IS MONTE CARLO SIMULATION FREE
When the resulting free energy is lower or equal to the initial value, the new orientation replaces the former. Single-phase alloy grain growth simulation was carried out by calculating the free energy of each atom in the lattice (with its present crystallographic orientation) and comparing this value to another one calculated with a different random orientation. microstructural evolution depends only on the real topology of the grains and not on any kind of geometric simplification.Ĭomputer simulation has the advantage of allowing the user to visualize graphically the procedures, even dynamically and in three dimensions. the statistical behavior of the atoms is properly reproduced Grain growth simulation using this method is especially attractive as Monte Carlo methods have been used in computer simulations in many different fields of knowledge. Understanding and predicting grain growth in Metallurgy is meaningful. Mello Moraes, 2463 São Paulo - SP, Brazil Metalúrgica e de Materiais, Escola Politécnica da Universidade de São PauloĪv.
