Essay

Reception of high-resistant tools by caburisation of alloys of iron with chromium and titanium. Methods of reseach are optical and electronic microscopy, the X-ray analysis, X-ray microanalysis, mathematical modeling. The formation in surface layers of alloys Fe-(1,04-1,70%Ti) of the martensite-carbide composite at carburizing. The features of structure's formation of a composite, influence on it additional alloing, thermal treatment are investigated. The hardness and heart-resistance of carburized layers of reseach alloys Fe-Ti and Fe-Ti-Cr are determined. The technological processes of carburizations and final thermal treatment of tools are developed. A sphere of use are the tool and machine-building enterprises.
