FIELD: metallurgy.
SUBSTANCE: casting block is heated and it is implemented two-stage deformation with cooling on air. The second stage of deformation is implemented in isothermal conditions at temperature for 50-100 °C lower than temperature of the first stage at a rate 4·10-2-5·10-1 s-1 and with total degree of deformation 65-85%. Between the first and the second stages of deformation it is implemented treatment at a temperature 180-300°C during 1-12 hours.
EFFECT: received deformed semi-products differs by increased strength, plastic and corrosive characteristics at keeping of low anisotropy, that assist to increasing of resource, reliability of particular products from these semi-products, increases ability of its application.
