MULTI-FUNCTION ANTIFRICTION NANOSTRUCTURE WEAR-RESISTANT DAMPING ALLOYS WITH SHAPE MEMORY EFFECT ON METASTABLE BASIS OF IRON WITH STRUCTURE OF HEXAGONAL -MARTENSITE, AND ITEMS USING THESE ALLOYS WITH EFFECT OF SELF-ORGANISATION OF NANOSTRUCTURE COMPOSITIONS, SELF-STRENGTHENING AND SELF-LUBRICATION OF FRICTION SURFACES, WITH EFFECT OF SELF-DAMPING OF VIBRATIONS AND NOISES

摘要

FIELD: metallurgy. ^ SUBSTANCE: alloy contains the following, wt %: carbon 0.001 - 0.3, manganese 5.0 - 44.0, nitrogen 0.03 - 0.12, and iron is the rest; at that, its structure contains 5 - 95% of -martensite phase, and -austenite and/or -martensite is the rest. Alloy can also contain 0.5 - 8.0 wt % of silicium and/or cobalt and one or several elements of the group: titanium 0.06 - 1.0, vanadium 0.06 - 0.20 and niobium 0.05 - 0.20. ^ EFFECT: alloy has high damping and antifriction properties, wear resistance and shape memory effect, which allows using it for manufacture of items having the effect of self-organisation of nanostructure compositions on intense friction surfaces, effect of self-strengthening, self-lubrication, self-damping of vibrations and noises, which are used for operation at normal and negative temperatures. ^ 9 cl, 13 dwg, 4 tbl
