Abstract
This invention describes a process for producing copper alloys by rapid sdification in order to improve their strength and thermal stability after being exposed to elevated temperatures. The method used to rapidly solidify the molten alloy is either by use of a high pressure non-oxidizing gas spray to atomize the molten alloy into a powder or to pour the molten alloy onto a rotating wheel to form a ribbon which is then attrited into powder. The powder is canned, compacted to full density and cold worked to the desired shape.
