HIGH TEMPERATURE METAL ALLOY MIXTURES FOR FILLING HOLES AND REPAIRING DAMAGES IN SUPERALLOY BODIES

摘要

ABSTRACTA silicon-free metal powder mixture suitable forfilling holes, slots and widegap joints in hightemperature superalloys and/or for reforming damaged ormissing surface extensions thereof, and capable ofbeing processed at a temperature of about 2000°F. Thesemi-solid metal mixture has a sufficiently highsurface tension and viscosity to be essentiallynon-flowing at the processing temperature so that itretains its applied shape and location without flowingduring processing. The metal mixture after processinghas a solidus temperature of at least 1950°F.
