Mathematical Modeling of Thermomechanical Treatment Process Applied to Aluminum Base Alloys for Aeronautics

Abstract

To optimize the thermo-mechanical processing of aluminum base alloys, mathematical modeling was used in a laborious research program by planned experiment of thermomechanical treatment process applied to an Al-Zn system alloy. The paper presents the modeling stages, the type of mathematical model that allows for the analysis of the main influences (technological parameters), their influence size and the type of correlationsbetween them. The simulation of the thermomechanical treatment process by varying the process parameters within the tested values and thermomechanical treatment optimization (getting the optimal complex of strength and plasticity properties in a convenient treatment option) is possible using the mathematical model developed.
