This program is being conducted for the purpose of applying the principle of rapid solidification to aluminum and iron alloy powers and subsequent development of stronger alloy compositions for fan blade application Al alloys and higher speed bearing material Fe alloys. Centrifugal atomization and forced convective cooling are being used to produce the fast cooled powder. During this report period, adaptation of the RSR process to aluminum and ion systems was contained. Both Al and Fe alloys were produced and the Al alloys were consolidated by direct extrusion. Hardness and mechanical testing were begun for initial evaluation of aluminum alloys. Author
