抄録

We present results of a Monte Carlo simulation of the time evolution of the ordering process in an f.c.c. A₃B alloy, which undergoes the order-disorder phase transition. In our model system, nearest neighbor interactions are assumed to favor pair formation of A and B atoms. A and B atoms are initially arranged randomly on the f.c.c. lattice sites, then the system is quenched to and to be evolved at a finite temperature T. Exchanges of position of atoms are allowed between nearest neighboring atoms with the Markovian transition probability.The time variations of the distribution function of cluster size and the average value of cluster size are obtained. These are compared with the results obtained from X-ray diffraction studies. Near the transition temperature, the relaxation time for the number of ordered cells shows a kind of slowing down behavior.
