The microalloyed high-strength aviation alloy of the Al-Si-Cu system obtained using additional pressure on the melt during crystallization is studied in the work. The technology and design features of laminar filling of the mould are developed in order to minimize the formation of technological casting defects. The peculiarities of the structure and crystallization conditions of the AK9M2 alloy are studied. The level of physical-mechanical properties of obtained alloy and its fracture behaviour are determined. Mechanisms of heat transfer are analysed and determined, which allow the promising use of obtained alloys as a material for heat-exchange applications.
