Abstract

Fe₃₂Cr₆₈, Fe₄₂Cr₅₈, Fe₅₂Cr₄₈, Fe₆₂Cr₃₈ and Fe₇₂Cr₂₈ were synthesized by mechanical alloying (MA) of Fe powder and Cr powder using a planetary ball milling for 180ks in 1.33kPa argon gas atmosphere. In particular, the influence of milling time on structural phase of Fe₅₂Cr₄₈ has been studied. Because according to the phase diagram, a phase is expected to form on the composition of Fe₅₂Cr₄₈. As the Cr content of MA powder increased, the time for homogenization by MA became longer.<BR>These MA powders were compacted by Spark Plasma Sintering (SPS) process. Mechanical alloyed Fe₅₂Cr₄₈ was rapidly shrunk at above 800K and completely condensed above 1073K. Fe₅₂Cr₄₈ which compacted by SPS at 1073K had no pore and its density was 7.46g/cm₃.<BR>Fe-Cr alloy prepared by this process contained no σ-phase.
