Abstract

A sliding enhanced wear-resistance can be significantly achieved by reducing the content of Nb element in TiZrHfNb refractory high entropy alloys (RHEAs). The wear loss reduced by half from TiZrHfNb to TiZrHfNb_0.4. The wear loss is directly related to the subsurface instabilities induced by plastic deformation during friction. The origins can be attributed to two factors: i) plastic deformation induced grain refinement; ii) deformation-induced BCC to HCP phase transformation.
