PROCESS FOR FUSION WELDING A SUPERALLOY WORKPIECE AND METHOD OF HARD-FACING SUPERALLOYS WITH A WIRE PRODUCED BY RAPID LIQUID QUENCHING

摘要

A wire of a normally nonforgeable composition, having improved resistance to fracture during working, handling and use is comprised of a portion with a rapidly quenched structure as a continuous stratum along its length. A preferred wire useful for fusion welding has a circular cross section with a micro-crystalline surface portion of at least 30 volume percent of the wire. Other preferred wires have elliptical or rectangular cross sections with amorphous strata continuous along their lengths.
