The effect of cooling rate and content of niobium on the structure, wear and corrosion resistance of CoCrFeNiNbx high entropy alloys

Figure 1 shows the X-ray diffraction (XRD) patterns of the CoCrFeNiNb_x alloys solidified with different cooling rates. All of the alloys are characterized by the dual-phase microstructure consisting of face-centred cubic (FCC) solid solution and…
