Abstract
A method for improving the compaction characteristics of a substantially noncompactable metal powder comprising preparing a superalloy, for example, a nickel base alloy, minus a portion of at least one metal (i.e., 5 weight percent); atomizing the melt and milling it to a fine powder (i.e., about average Fisher size of 9.0 microns); blending an equal portion (i.e., about 5 weight percent) of, for example, carbonyl nickel into the milled powder; sinterbonding the mixture into a 'cake' and then further processing as may be required to obtain the desired article. It is believed the 'soft' carbonyl nickel acts as a binder for the prealloyed nickel-base alloy powder.
