СПОСОБ СТАРЕНИЯ ЖАРОПРОЧНЫХ СПЛАВОВ

摘要

FIELD: metallurgy. ^ SUBSTANCE: invention relates to machine - building and can be used in mechanical manufacturing to cutting the defails from grade of alloy "¡ÿ787 (Ñ35Æ«)" after their ageing. Alloy is heated at high temperature and successively cooled in air; further alloy is annealed at low temperature of 200C during 3 hours, cooled in air, aged by means of heating to temperature of ageing; and conditioned at this temperature with successive cooling in air. ^ EFFECT: restriction of hardness growth and improvement of machining quality. ^ 1 tbl, 1 dwg
