Prediction of precipitation hardening of sheets from aluminum alloy V-1341 of the Al – Mg – Si system with the help of mathematical modeling is considered. Special features of decomposition of the supersaturated solid solution (SSS) of the alloy are investigated by thermal analysis and electron microscopy with the aim to determine the unknown parameters of the mathematical model. It is shown that the method suggested makes it possible to predict reliably the precipitation hardening of sheets depending on the rate of the quenching cooling. Computation is used to plot a diagram of isothermal phase transformations in decomposition of the SSS of the alloy and a temperature-time-property diagram applicable for selection of modes of quenching cooling for articles from alloy V-1341.
