Objects comprising Al-7.5 Mg particulate having pressure consolidated nanocrystalline coating material are formed. Oxides of the coating material, in particulate form, may become dispersed in the pressure consolidated, thereby increasing its strength.

Nanocrystalline aluminum alloy metal matrix composites, and production methods

Objects comprising carbide particulate having pressure consolidated nanocrystalline coating material are formed. Oxides of the coating material, in particulate form, may become dispersed in the pressure consolidated object, thereby increasing its strength.

Nanocrystalline aluminum metal matrix composites, and production methods

The method of consolidating a body in any of initially powdered, sintered, fibrous, sponge, or other form capable of compaction, that includes providing flowable pressure transmission particles having carbonaceous and ceramic composition or compositions; heating particles to elevated temperature; locating the heated particles in a bed; positioning the body at the bed, to receive pressure transmission; effecting pressurization of the bed to cause pressure transmission via the particles to the body, thereby to compact and consolidate the body into desired shape, increasing its density, 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, aluminum, the consolidated body having, along a body dimension, one of the following characteristics: decreasing strength, increasing strength, or decreasing ductility (strain hardening) and increasing ductility (strain hardening).

Metal consolidation process applicable to functionally gradient material (FGM) compositions of tantalum and other materials

A method of consolidating metal powder to form an object that includes pressing the powder into a preform, and preheating the preform to elevated temperature; providing flowable pressure transmitting particles and transmitting microwaves into the particles to heat same, and providing a bed of the flowable and heated pressure transmitting particles; positioning the preform in such relation to the bed that the particles substantially encompass the perform; and pressurizing the bed to compress the particles and cause pressure transmission to the preform, thereby to consolidate the preform into a desired object shape, the powder of step a) consisting essentially of at least two of the following: W, Ni, Fe, Co, manganese and titanium, and preferably at least three of same.
