ABSTRACT:
Disclosed are metal powders mixtures which can be mechanically alloyed into oxide dispersion strengthened high temperature alloys. The powder mixtures contain from 0 to 30 wt. % chromium, about 0 to 3 wt. % titanium, about 0.3 wt. % to 10 wt. % aluminum, and from about 0.3 wt. % to 10 wt. % particles of one or more alumina-yttria mixed- oxides selected from the group consisting of Al.sub.2 O.sub.3.2Y.sub.2 O.sub.3, Al.sub.2 O.sub.3.Y.sub.2 O.sub.3, and 5Al.sub.2 O.sub.3.3Y.sub.2 O.sub.3.
