AGE HARDENABLE DISPERSION STRENGTHENED ALUMINUM ALLOYS

摘要

Dispersion strengthened aluminum-cerium-manganese alloys containing from about 0.05 to about 23.0 weight percent cerium and about 0.03 to about 9.5 weight percent manganese exhibit mechanical properties that make them useful alloys as a result of age hardening for extended periods at temperatures between 350° C (662° F) and 450° C (842° F).
