Abstract

The results of modeling and experimental research of the hot isothermal pressing process of various thicknesses strips from cast cylindrical blanks of 1570 and 1545 alloys of Al-Mg-Sc system are presented. The temperature-force parameters of the process and the pressed strip geometry to obtain its minimum damage are established. It is shown that during pressing of a ∅ 30 mm workpiece at 360°C the calculated damage ω = 0.35–0.45 for a strip with a cross-section of 30×12 mm without visually observable surface cracking. In the strip with a cross-section of 30×6 mm at ω = 0.50–0.55, macrocracks are recorded.
