ABSTRACT:
Powder composed of particles of a rapidly solidified dispersion strengthened aluminum base alloy is compacted into billet form. The billet is vacuum autoclaved at a temperature ranging from 350.degree. C. to the alloy's incipient melting temperature and formed into a substantially fully dense wrought product. Gas content of the alloy is decreased and powder degassing steps are eliminated. The dispersion strengthened aluminum wrought product is produced in an economical and efficient manner.
