English Abstract

Enhancing microstructural evolution as a result of aging of engineering alloys controls their reliability as mechanical, electrical and thermal interconnects in electronics industry.

To be able to regulate the electronic component reliability as well as to predict the performance of proposed designs rely on the development of reliable materials models.

The Monte Carlo Potts model was developed to simulate Ostwald ripening in two-phase solid-liquid materials.

Ostwald ripening is simulated by treating two phases, solid grains dispersed in a liquid matrix as a two-dimensional square array of sites.

Each site of the solid-phase grains (phase A) is given a random positive number between 1 and Q where Q = 100 for all the simulation.

The sites of the liquid phase (phase B) are assigned only one negative number, qB = -1.

It is found that the grain growth is controlled by volume diffusion for volume fraction of the solid grains ranging from 40 % to 90 %.

The grain growth exponent has the value, n = 3, in agreement with the theoretical value of ostwald ripening.
