Abstract

The relationship between the elementary excitation energy and the transition temperature was analyzed using Monte Carlo simulations. It was observed that the materials properties including fracture strength, impurity diffusion, and corrosion resistance were affected by the structure of grain boundaries (GB). It was also observed that the GB defaceting transition differs from the surface roughening transition. It was shown that the grain boundary stress is too small to stabilize finite GB facets which suggested that the existing theory of GB defaceting phase transitions is incomplete.
