Abstract
A floating magnet model [5, 6] originally devised for simulating effects in superconductors has been modified to simulate metal and alloy lattices. The model shows grain boundaries, edge dislocations and point defects in the metal lattice, demonstrating the pinning of dislocations by impurity atoms and the drift of impurities to grain boundaries. Although the alloy was disordered for most concentrations, a stable ordered square lattice was formed readily at equal proportions of the two atoms. Defects, particularly dislocations, were more complicated in the ordered alloy than in the simple metal.
