Paper Title:
Research on Frictional Wear Property of the High Vanadium High Speed Steel in Conditions of Low Slip-Roll Ratio
  Abstract

The frictional resistance and abrasion mechanism of high vanadium high speed steel were studied by the self-made friction wear testing machine under the conditions of 0.5% slip-roll ratio. Results show that the frictional resistance increases with the increase of carbon content. The retained austenite and the shapes of carbides will change when the carbon content alters, which make the frictional resistance of the material change, and the proper quantities of retained austenite makes the impact toughness the matrix better; The spherical VC can prevent the initiation and expansion of cracks forming and make the frictional resistance increase. The abrasion mechanism is fatigue flake under the condition of rolling and sliding.
