Molybdenum and graphite powders were mechanically alloyed. Carbon K X-ray emission spectra of the mechanically alloyed powders were measured using electron probe microanalyzer (EPMA) in order to investigate the solid state reaction process. In the early stage of the mechanical alloying (∼ 36 ks), graphite did not react with molybdenum, but particle size of graphite became smaller. In the next stage of mechanical alloying (36∼144 ks), graphite react with molybdenum gradually as the time increases. Molybdenum carbides were formed on mechanical alloying for 288 ks. The mechanically alloyed powders for 288 ks were heat-treated in a vacuum. Mo–33 at%C system heat-treated at 1273 K was a mixture of Mo<SUB>2</SUB>C and molybdenum, while Mo–50 at%C system heat-treated was a mixture of Mo<SUB>2</SUB>C, mechanically ground graphite and graphite.
