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 powder and subsequent development of stronger alloy compositions for fan blade application (Al alloys) and higher speed bearing materials (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 iron systems was continued. The evaluation of the first aluminum alloy matrix was partially completed, and a second matrix was selected. Hardness testing and microstructural evaluation of Fe alloys was performed. (Author)
