Abstract

Oxide dispersion-strengthened (ODS) alloys are produced by mechanical alloying of fine inert oxide pArticles in a highly alloyed matrix to produce composite metal powders with a controlled microstructure. The process involves repeated fracturing and rewelding the mixture of powder pArticles in a highly energetic ball charge. This Article discusses the production, consolidation, property development, fabrication of mill products, and joining of mechanical alloying ODS (MA ODS) alloys. It also describes the nominal composition, microstructure, mechanical, physical, oxidation and hot-corrosion properties of different types of mechanically alloyed (MA) commercial alloys having nickel, iron, and aluminum-base alloy systems, namely, MA 754, MA 758, MA 956, MA 6000 and MA 760.
