PROCESS OF PRODUCTION OF HIGH-DENSITY MATERIALS AND ARTICLES BY REACTION SINTERING UNDER PRESSURE Russian patent published in 1998 - IPC

Abstract RU 2119847 C1

FIELD: powder metallurgy. SUBSTANCE: process includes preparation of mixture of powders of exothermic composition, pressing out of burden billets from mixture, their placement into porous heat insulating shell, initiation of burning reaction and sintering of combustion products under pressure in shell. Burden billets are clad by exothermic substance with gaseous combustion products. EFFECT: diminished thickness of heat insulating shell and increased rigidity of deformed medium and dimensional precision of articles.
