Publication number: 20170058386Abstract: Aluminum-zirconium and aluminum-zirconium-lanthanide superalloys are described that can be used in high temperature, high stress and a variety of other applications. The lanthanide is preferably holmium, erbium, thulium or ytterbium, most preferably erbium. Also, methods of making the aforementioned alloys are disclosed. The superalloys, which have commercially-suitable hardness at temperatures above about 220° C., include nanoscale Al3Zr precipitates and optionally nanoscale Al3Er precipitates and nanoscale Al3(Zr,Er) precipitates that create a high-strength alloy capable of withstanding intense heat conditions. These nanoscale precipitates have a L12-structure in ?-Al(f.c.c.) matrix, an average diameter of less than about 20 nanometers (“nm”), preferably less than about 10 nm, and more preferably about 4-6 nm and a high number density, which for example, is larger than about 1021 m?3, of the nanoscale precipitates.Type: ApplicationFiled: September 12, 2016Publication date: March 2, 2017Applicants: NanoAL LLC, Northwestern UniversityInventors: Nhon Q.
