Abstract:
In the method of consolidating a body in any of initially powdered, sintered, fibrous, sponge, or other form capable of compaction, that includes the steps:a) providing flowable pressure transmission particles having carbonaceous and ceramic composition or compositions, b) heating said particles to elevated temperature, c) locating said heated particles in a bed, d) positioning said body at said bed, to receive pressure transmission, e) effecting pressurization of said bed to cause pressure transmission via said particles to said body, thereby to compact and consolidate the body into desired shape, increasing its density; f) the body consisting essentially of one or more metals selected from the following group: tungsten, rhenium, uranium, tantalum, platinum, copper, gold, hafnium, molybdenum, titanium, zirconium and aluminum; g) said consolidated body having, along a body dimension, one of the following characteristics: i) decreasing strength ii) increasing ductility iii) decreasing strength, and increasing ductility.
