METHOD OF SINTERED BARS PRODUCTION FROM HEAVY ALLOYS ON BASIS OF TUNGSTEN Russian patent published in 2008 - IPC B22F5/10 B22F3/12 B22F3/24 B22F7/02

Abstract RU 2336973 C2

FIELD: technological processes; metallurgy.

SUBSTANCE: method includes preparation of uniform mixture of powders that contains not more than 92 wt % of tungsten, the rest is nickel and iron, and bar pressing. After bar pressing wafer is forced on its surface with tungsten content of 94 - 98 wt %, the rest is nickel and iron or copper, and than item is sintered.

EFFECT: reduction of deformation of sintered thin-walled complex-shaped large-size items and reduction of metal surplus for mechanical processing.
