Abstract:
The paper presents the results of studies of the influence of the Zn:Mg ratio on the hardenability, structure and complex of mechanical and corrosive characteristics of forgings with 150 mm thickness made of alloys based on Al–Zn–Mg–Cu system, manufactured in the production conditions of metallurgical plants of JSC AMR and Public Corporation “KUMZ”. It has been determined that an alloy of the Al–Zn–Mg–Cu system with Zn:Mg ratio of not less than 4,1:1 and copper mass content of not more than 1.2% has a higher hardenability compared to the 1933 alloy of standard composition, which ensures homogeneous structure and indicators of mechanical and corrosion properties over the thickness of semi-finished pro-ducts; in metallurgical industry at the stage of manufacturing this allows reducing the residual quenching stresses in massive forgings by means of straightening by reduction in an as-quenched state.
