Abstract


Order-disorder transformation in alloys is a fascinating and extensively studied problem for many years. This transformation has been studied widely using the two state Ising model. But vacancies are not considered in two state Ising model, which may play an important rule in determining the composition of stable configuration. So we used three state Ising model which takes vacancies also at lattice sites. To make a realistic study we have
included kinetic energy of the particles in the total Hamiltonian.


Keywords


Ising model, binary alloy, order-disorder transition
