Microstructure of a Rapidly Solidified Al-Fe-Co-Ni Alloy

Abstract

Observations made on different consolidated and wrought mlcrostructures suggested that in addition to the simple variations in size and size distributions there were also differences in shape. Furthermore, clusters of oriented precipitates were often observed. The different particle morphologies were related to solidification rate effects. This paper describes the changes in microstructure which occur during the heating of rapidly solidified Al-3.3Fe-4.6Co-2.3Ni splat.
