FIELD: metallurgy.
SUBSTANCE: ingot with diameter of 400-800 mm and length of 2-3 m is produced by means of casting; then ingot is forged in one operation at temperature corresponding to region of α- and β-phases of alloy. Flat items are fabricated out of semi-finished product of 0.2-4 mm thickness such as plate of cross grating-bridge of nuclear fuel reactor assembly cooled with water under pressure, or wall of the case of fuel reactor assembly cooled with boiling water or element of fuel reactor assembly CANDU.
EFFECT: invention allows to simplify and reduce cost of items fabrication, also to reduce hydrides contents in semi-finished product.
