Abstract

This paper presents results of research on optimization of thermomechanical treatment applied to an alloy of the Al-Zn-Mg-Cu system, used in the aviation industry. Optimizing thermomechanical treatment process is based on a mathematical model that establishes the relationships between the main technological parameters of thermomechanical processing and association of physical and mechanical properties of the alloy used. Findings are based on an laborious experimental program to elaborate the mathematical model, an essential element of thermomechanical treatment process optimization applied to the alloy studied for obtaining the required values of mechanical properties with the minimal cost.
