Alloys in the Fe-Al-C system were prepared by quenching from 1800 K to 298 K at 6 GPa pressure. Phase relations were investigated under normal conditions by means of X-ray diffractometry, microprobe analysis and metallography. According to the results of the experiments, a scheme of phase relations in quenched alloys of the Fe-Al-C system was suggested over a full concentration range. One ternary compound (Fe 3 AlC), three high-pressure phases (FeAl 6 , Fe 7 C 3 and C diamond ) and several binary compounds (Al 4 C 3 , Fe 4 Al 13 , Fe 2 Al 5 , FeAl 2 , FeAl, Fe 3 Al and Fe 3 C) were identified. |
