Rolling/sliding Wear Property and Failure Behavior of High-vanadium High-speed Steel for Rolls
轧辊用高钒高速钢的滚-滑动磨损性能及失效行为研究

Under rolling/sliding condition(with slip ratio of about 10%),the wear property of high-vanadium high-speed steel(HVHSS) was studied via wear testing machine developed by authors,and the failure behavior was analyzed via electron microscope.Results show the relative wear resistance of HVHSS is twice higher than that of high-chromium cast iron(Cr20).The wear failure is mainly caused by the combined action of micro-cutting and fatigue desquamation,with fragmentation of carbides.Carbides play a important role ...
