Understanding the effects of carbon addition on mechanical and wear properties of TiMoNbZr alloy
In order to enhance mechanical and tribological properties, carbon was microalloyed in a series of TiMoNbZrCx (x = 0, 0.03, 0.05, & 0.09 wt%) based refractory high entropy alloys (RHEAs). All the RHEAs exhibited BCC as major phase with minor cubic carbide phases in C added samples. Increase in C content tend to refine microstructure attributted to Zenner pinning effect, and further enhance its hardness (from ∼610 to 727 Hv) and yield stength (from ∼1668 MPa to 1990 MPa). The lean C (0.03 wt%) content enhanced in-vitro wear resitance by an order, while higher C addition accompanied an increase in wear rate ascribed to carbide assisted third body abrasion.
