Purpose: The microstructure characterization of iron-carbon powder and sinters is the purpose of this paper. The main aim of this work is to determine structure of Fe-0.8% mass. C alloys. Design/methodology/approach: Iron-carbon powder alloys were produced employing the mixture of crystalline iron and graphite powders in suitable weight relation. The powders were mechanical alloyed and sintered. The pressing and free sintering were applied. The X-ray diffraction, scanning electron microscopy and optical microscopy investigations were performed on Fe-0.8% mass. C alloys. Findings: The application of the mechanical alloying method enables to produce nanocrystalline alloys with amorphous phase. The choose of sinter method have an influence on structure of sinters. The free sintering process in the temperature of 1100 degrees causes the crystallization of cementite and forming of voids. Research limitations/implications: The powder metallurgy techniques make it possible to obtain Fe-C massive materials by means of HEBM (High Energy Ball Milling), followed by compacting and sintering. Further investigations should be concentrate on the developing of powder consolidation method and refinement particles during high energy ball milling. Originality/value: The determination of the relations between the powders and sinters structure is necessary for the proper procedure of material manufacture and indication of the fields of their application.
