Abstract
This paper presents studies regarding the behaviour at heat treating of an AlCu4Mg1 aluminum alloy. The experiments were made on laboratory conditions and can be applied in industry. The proposed methodology can be resumed in: adopting the heat treating technology for the proposed alloy; choosing the necessary working installations in order to realize the heat treating for the specified alloy; choosing the tools and the machines used for studying the chemical and mechanical characteristics; programming the experiment and analytical interpretation of the results. For experiments, was used a study charge (9 treated parts) and a test part (a non treated part). Every part from the study charge had a particularly final heat treating technology. Test part is not treated and the mechanical characteristics are determined in this situation. As a conclusion, the paper presents the algorithm for applying the optimum heat treating in order to obtain the necessary properties for the working parts.
