Abstract

The results of developing a technology for manufacturing of pressed and forged semi-finished products from a hard-to-deform aluminum alloy of the Al–Si–Ni system, grade SAS1 for rocket and space technology products are presented. Taking into account the capabilities of the equipment of the National Research Center «Kurchatov Institute» – VIAM, a technology has been developed for the production of pressed semi-finished products and forgings with a diameter of up to 50 mm. The manufactured pressed semi-finished products have the following level of physical and mechanical properties: d = 2,7 g/cm3, σв = 325–335 MPa, σ0,2 = 210–230 MPa, δ5 = 1,6–2,1 %, α ≤ 14,4·10–6 К–1
