Aluminum-transition metal alloys made using rapidly solidified powers and method |
摘要 |
A method of fabricating aluminum alloys containing finely dispersed aluminum-transition metal intermetallic phases is disclosed. The alloys are subjected to melt spinning to form a brittle filament consisting in large measure of a metastable face-centered cubic solid solution; this is then pulverized to a staple or powder configuration; the power or staple is consolidated using conventional techniques. Upon heat treatment, the solid solution decomposes into a structure consisting of an aluminum alloy matrix of conventional composition containing a fine uniform dispersion of the intermetallic phase, the heat-treated alloy being ductile. The heat-treated alloys possess high strength, especially at elevated temperatures. Preferred alloys are disclosed which contain 10 to 15 wt % Fe.
