| Abstract | Structure, phase compositions and heat-physical properties of ЧЮ22Ш (ChYu22Sh) high-alloyed iron with globular graphite are examined. It is shown that iron is crystallizing as eutectic alloy where eutectic from α-solid solution and graphite makes the base of it's structure. Iron-aluminium carbide is presented as secondary phase. In this case α-solid solution is characterized by 410 HV microhardness and contains appr. 23 % Al, while iron-aluminium carbide with 650 HV microhardness is ε-phase similar to Fe1.5AlCx in its composition. |
