PRODUCT MADE OF DEFORM HIGH-STRENGTH ALLOY Al-Zn AND MANUFACTURING METHOD OF SUCH PRODUCT Russian patent published in 2009 - IPC C22F1/53 C22C21/10 

FIELD: metallurgy.

SUBSTANCE: presented invention relates to product made of deform high-strength alloy Al-Zn and also manufacturing method of product made of this alloy. Product is implemented for steel containing following ratio of components, wt %: zinc 7.6-9.5, copper 1.3-2.4, magnesium 1.5-2.6, manganese 0.06-0.12, zirconium < 0.20, chrome < 0.10, iron < 0.25, silicon < 0.25, titanium < 0.10, hafnium and/or vanadium < 0.25 and it is not necessary cerium and/or scandium < 0.20, inevitable admixtures - less than 0.05 of each and less than 0.25 in total, the rest - aluminium, with 0.1[Cu]+1.3<[Mg]<0.2[Cu]+2.15. Method of product manufacturing includes ingot casting with above mentioned content, pre-heating of ingot after casting, ingot hot working by pressure and not obligatory fabrication till pressure workpiece, thermal processing to solid solution and hardening of heat-treated to solid solution of product. IT is received product allowing high tensile and improved combination of viscosity and corrosion behavior.

EFFECT: receiving of product allowing high tensile and improved combination of viscosity and corrosion behavior.
