ELETRODEPOSITED DISPERSION-HARDENED ALLOYS—KEY TO HIGH-TEMPERATURE STRENGTH IN CLAD PIECES (AN EVALUATION OF COMMERCIAL APPLICATIONS)

摘要

A new technique has been developed for the preparation of dispersion-hardened alloys. Working with the Ni-Al203 alloy system, government researchers have electrodeposited uniformly dispersed sheets of this material, varying from 400 angstroms up to 3/8-inch in thickness. Using submicroscopic Al203 particles, the room-temperature yield strength increased from 10,000 psi for pure nickel to 40,000 psi for an alloy containing 2% Al203.nThe applications interest in the process ranges from the lining or cladding of other metallic materials to the actual production of complex shapes by electroforming.
