Abstract
A silicon-free metal powder mixture suitable for filling holes, slots and widegap joints in high temperature superalloys and/or for reforming damaged or missing surface extensions thereof, and capable of being processed at a temperature of about 2000.degree. F. The semi-solid metal mixture has a sufficiently high surface tension and viscosity to be essentially non-flowing at the processing temperature so that it retains its applied shape and location without flowing during processing. The metal mixture after processing has a solidus temperature of at least 1950.degree. F.
