Application of Rapidly Solidified Alloys.

Abstract

This program is being conducted for the purpose of applying the principle of rapid solidification to aluminum and iron alloy powders 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 that RSR process to aluminum and iron systems was begun. Both Al and Fe alloys were produced and the Fe alloys were consolidated by direct extrusion. Heat treat study and hardness testing were used for preliminary evaluation of iron alloys.
