•The addition of Si element is beneficial for the formation of BCC phase.•Si1.0 HEAs has the highest micro-hardness and the best wear resistance.•The wear mechanism changes from oxidation wear and abrasive wear to abrasive wear. In present research, the phase evolution and mechanical properties of F...
