METHOD OF PREPARING OF POWDER ALLOY ON COPPER-BASE Russian patent published in 1994 - IPC

Abstract RU 2015851 C1

FIELD: metallurgy. SUBSTANCE: method involves preparation of powder charge by mixing of powders of chrome, zirconium and copper with titanium carbide powder (particle size of latter component is 1 micron, not more) at the following ratio of components in the charge, wt.-%: chrome 0.4-1.0; zirconium 0.1-0.8; titanium carbide 0.5-1.0, and copper - the rest. Powder charge is pressed, heated up to 1000-1050 C, kept for 2-3 h and extrudated with stretching coefficient λ≥ 3 at the same temperature. EFFECT: improved method of powder alloy preparing. 2 tbl
