The primary DRPHS configuration are relaxed with Lenard-Jones and Morse potential respectively for Co81P19 and Ni64B36 amorphous alloys. Two displacement fraction f=0.005 and f=1 are considered in the case of Ni64B36. Total energy, reduced partial distribution function and angular distribution function are obtained from the calculated data. Effect of localization and correlation of potential function on chemical short range order in binary amorphous alloys are discussed.
