Effects of temperature and microstructure on the triblogical properties of CoCrFeNiNbx eutectic high entropy alloys

This paper is aimed to evaluate the high temperature tribological behaviors of CoCrFeNiNbx eutectic high entropy alloys which would be highly-promising candidates for high-temperature applications. The effects of testing temperature and material structure on the friction and wear properties are investigated. The CoCrFeNiNbx alloys display a low harness decrement rate about 35% from room temperature to 1000 °C, indicating good softening...
