Mechanosynthesis of Nanocomposites Based on Fe-TiC and Fe-TiN in Hydrocarbon Medium

摘要

In this paper the nanocomposites based on Fe-TiC and Fe-TiN which were produced by mechanosynthesis of the mixture of Fe or Fe-N (82 at.%) and Ti (18 at.%) in toluene for 16 h and subsequent compaction have been studied. The structural-phase composition and morphology of the mechanosynthesized powders were studied by X-ray diffraction analysis, the Mossbauer spectroscopy and electron microscopy. It has been shown that powders of the following composition: a solid solution based on Fe, TiC or TiN, a phase on the basis of Fe_3C - are formed by mechanosynthesis. The measurements of microhardness and corrosion resistance of the produced compacts were carried out as well.
