Abstract
Mechanical alloying of FeAl intermetallic performed with stearic acid as process control agent results, after sintering, in high volume frac tion of perovskite-type Fe3AlCx carbide, unsuitable for ductility and creep strength purpose. Two methods have been developed to eliminate t his carbide : one based on zirconium hydride addition and the other on suppressing stearic acid from MA process. Additionally, unit cell par ameter and carbon content in Fe3AlCx carbide have been established and confronted with values given by 29-44 ASTM standard.
