Заглавие: STUDY OF THE BEHAVIOUR OF ALUMINIUM-SILICON ALLOYS INTERFUSED WITH CU AND MG AT HIGH TEMPERATURES
Ключови думи: aluminium-silicon alloys, interfusion, complex modification,high-temperature tests

Абстракт: Aluminium-silicon alloys with eutectic and hypereutectic composition have been interfused with copper and magnesium. The alloys AlSi11Cu5Mg and AlSi18Cu5Mg have been complexly modified. The complex modifying treatment with P, Ti, B and Be aims not only at modifying the structural components of the alloys, but also at creating conditions, conductive to formation and separation of the strengthening phases. The studied silumins have been subjected to T6 heat treatment, consisting in hardening and artificial ageing. The tensile strength of the tested compositions has been determined at high temperatures – 200°С, 250°С and 300°С. Evaluation of the obtained results has been made.
