Abstract

1508350 Compacting metal powder NATIONAL RESEARCH DEVELOPMENT CORP 27 Oct 1976 [4 Nov 1975] 45778/75 Heading C7D Metal powder such as Fe, Ni, stainless steel, Co, Pb or Mo is compacted by discharging a capacitor through it. As shown in the Figure the capacitor 3 is discharged via electrodes 5, 6 through the metal powder 1 packed in a glass or paper tube 2. The maximum current density through the powder is 1250 A/mm<SP>2</SP>, the density of the compact being at least 50%. A conductive cylinder may be placed around the tube to increase the induced magnetic field and the compact may be swaged without intermediate annealing.
