Abstract—The effects of alloying with 1–2 wt % of vanadium or molybdenum on the structure, strengthening,
and wear resistance of a steel with 0.8 wt % of carbon were studied after laser and volume quenching and tem-
pering at 75–700°C. It was established that, unlike molybdenum, vanadium increases the abrasive resistance
(by up to 70%) and strain-hardening of high-carbon martensite. This may be caused by the influence of vana-
dium on the efficiency of dislocation pinning with impurities in the as-quenched martensite upon wear. Upon
the adhesive interaction under the conditions of extremal plastic deformation, the vanadium-containing untem-
pered quenched steel is characterized by a decreased wear resistance because of its increased brittleness. The
precipitation of fine vanadium and molybdenum carbides upon secondary hardening somewhat increases the
wear resistance of high-carbon steel.
