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.
Claims15
A process for reducing the gas content of a dispersion strengthened aluminum base alloy, comprising the steps of:
- (a) compacting a powder Composed of particles produced by rapid solidification of said alloy to obtain a compacted billet having a density varying from 70% to 98% of full density;
- (b) vacuum autoclaving said compacted billet at a temperatures ranging from 350.degree. C. to the alloy's incipient melting point;
- (c) forming said billet into a substantially fully dense wrought product.
