Abstract
1449978 Refractory metal containing bodies PR MALLORY & CO Inc 4 Oct 1974 [23 Oct 1973] 43151/74 Heading C7D A body comprising a major amount by weight of particles of Ta, Mo or W or a refractory compound thereof (e.g. a carbide) in a minor amount by weight of a metal matrix comprising Ta, Mo or W and one or more of Ni, Fe, Co, Cu, Cr the average particle size of the particles being substantially the same as their average particle size prior to the formation of the body. The body may be prepared by forming a porous shaped skeleton of the refractory metal particles (e.g. by pressing at 10 t.s.i. and sintering at 1460C in hydrogen for 4 hours) and adding the matrix alloy in an amount in excess of that required to fill the voids in the porous skeleton and heating the skeleton and matrix alloy in a hydrogen atmosphere to 1,000-1100C for one hour at 1,000-1100C followed by ¢ hour at 1450-1480C, cooling and machining off the excess matrix alloy from the body. The Examples include the use of W and Mo particles and matrix alloys of composition:- 40% Mo 20% Fe 40% Ni; 40% W 20% Fe 40% Ni; 28.5% Mo, 28.5% Cu 28.5% Ni 14.5% Fe; 40% Mo 40% Co 20% Fe. The product may be used in aircraft counterbalances, radiation shielding, gyroscopic inertia members and die casting dies.
