PROCESS OF MOULDING OF POWDERY MATERIAL BY EXPLOSION Russian patent published in 1994 - IPC

Abstract SU 1385392 A1

FIELD: powder metallurgy. SUBSTANCE: powder is poured into ampules. Damping filling agent with acoustic stiffness less than that of powdery material is placed between ampules. Thickness of diaphragm is chosen from ratio W = ρhо

U^h/ρ^k/ρkо

U^k ,, where ρhо

U^h is acoustic stiffness of powdery material; ρkо

U^k is acoustic stiffness of diaphragm. After arrangement of porous filling agent between walls of ampules openings on both sides are closed with end-pieces. The whole of container is positioned in flat charge and explosion is conducted. EFFECT: enhanced compactness and homogeneity of manufactured articles. 1 dwg, 2 tbl
