Abstract
Abstract
In this research, the wear behavior and microstructural transformation of approximately single face-centered cubic phase AlCoCrFeNi high-entropy alloy at elevated temperatures (∼25–600 °C) were investigated in detail. The combined action of environmental temperature and friction force can induce significant and regular transformation of the preferred orientation of crystalline grains at the high-entropy alloy friction interface. Generally as the temperature rises its principal wear mechanism varies fairly regularly from abrasive wear to delamination wear, and then to adhesive wear. It is worth noting that at a test temperature of 100 °C the wear debris formed during friction was rolled repeatedly and then separated by delamination, which played a pivotal role in inhibiting wear. Furthermore, five specific wear mechanisms of face-centered cubic phase high-entropy alloy at elevated temperatures have been elucidated through this study.
