Processing and fabrication of Fe sub 3 Al-based alloys
The Fe{sub 3}AL-based iron-aluminide alloys offer excellent oxidation and sulfidation resistance. The commercial applications of these alloys require additional information about their processing and fabrication. This paper presents information regarding alloy compositions, melting, and fabrication. The melting described is of experimental heats and scale-up heats at several vendors. Data about the recovery of alloying elements and the impurity pick-up during various melting processes are presented. Details are presented of a study conducted at Special Metals Corporation on the melting of heats in two different crucible materials and by three different processes. Brief descriptions are also given about forms from these ingots. 2 refs., 6 figs., 6 tabs.
