Abstract

The laboratory experiments were made on the two aluminium alloyed qualities used for aeronautical industry. The structure and mechanical characteristics were analyzed and the gotten results were compared using those two types of the thermal treatments. Also, the conventional thermal treatment was used, consisting of the solution quenching and artificial heat ageing, mode in more working condition. A significantly improvement of the mechanical characteristics was ascertained  to the thermical treated test-specimen.
