j i X?!!1 V ?? l?pI 11 i f y i / l ? ) We present results of a Monte Carlo simulation of the time evolution of theordering process in an fc.c. A,B alloy, which undergoes the order-disorder phasetransition. In our model system, nearest neighbor interactions are assumed tofavor pair formation of A and B atoms. A and B atoms are initially arrangedrandomly on the fc.c. lattice sites, then the system is quenched to and to beevolved at a finite temperature 'II Exchanges of position of atoms are allowedbetween nearest neighboring atoms with the Markovian transition probability.The time variations of the distribution function of cluster size and the averagevalue of cluster size are obtained. These are compared with the results obtainedfrom X-ray diffraction studies. Near the transition temperature, the relaxation timefor the number of ordered cells shows a kind of slowing down behavior.
