In this research, the results of kinetic study of phase precipitation on aging Al-Mg-Si alloy are presented. The results of the kinetic analysis of the process show that the formation of phases in the alloy is explained by the phase transformation kinetics. By the calculation results based on the hardness value, the coefficients K, n, Q were determined at different temperatures and aging times. The determination of these coefficients helps to determine the formation of phases in aging conditions. Also by the method of hardness measurement, the functions of phase transformation kinetics have been determined as well as the formation of different phases at each aging temperature of the studied alloy. Determining the kinetics of the phase formation when aging plays an important role in determining the formation as well as controlling the phase formation under different conditions.
