抄録

Fe-48at%Cr alloy powders were synthesized by mechanical alloying (MA) of elementary Fe powder and Cr powder using a planetary ball milling at various times under 1.33kPa argon gas atomosphere. The obtained MA powders were consolidated at 1123K for 0.3ks by spark plasma sintering (SPS) process and rectangular sintered bodies having a size of 30 mm long, 5 mm wide and 2 mm thick were prepared. Tensile specimens were prepared from these sintered bodies by grinding. The results of the tensile test, the tensile strength increased and the elongation decreased in MA-SPS process as the milling time of MA increased. It is conjectured that oxygen and nitrogen were mingled during the MA process. The tensile strength of Fe-48at%Cr alloy prepared by MA-SPS process using MA powders milling for 360ks was about 1045MPa and the elongation of that was about 11%. Fe-48at%Cr alloy prepared by this process existed no σ phase.
