MATHEMATICAL MODELLING OF HEAT TREATMENT PROCESS APPLIED TO Al-Zn-Mg-Cu ALLOY WITH A 2,6% Zn CONTENT, USED IN AERONAUTICS

摘要

This work presents the results of the researches concerning the mathematical modeling of the heat treatment process applied to an alloy belonging to the Al-Zn system, used in Aeronautics. The mathematical model presented in this work allows the simulation of the heat treatment process by variation of the technological parameters values within the experimental limits with a view to predicting the values of the mechanical properties. Also, on the basis of the mathematical model obtained, the optimization of the technological parameters can be achieved in order to obtain some imposed values of the mechanical properties with minimum costs.
