N2 - NiCoAlFeCu, NiCoAlFeCuCr, and NiCoAlFeCuCrTi high-entropy alloys are prepared by mechanical alloying and sintered at 12000C and a pressure of 1.5 GPa for 3 h. The alloys were characterized by X-ray diffraction (XRD), electron backscatter diffraction (EBSD), and X-ray energy dispersive spectrometry (XEDS). The phases found are mostly variants of the face centered cubic (fcc) phases (space group Fm 3m), bcc (space group 1m 3m), and hexagonal (space group P63/mmc). Adding Ti to the NiCoAlFeCuCr system has strong effects on the solubility of the elements in the different phases and increases dramatically the number of phases present. The use of EBSD and XEDS allowed identification of a cubic phase in NiCoAlFeCu samples, which cannot be identified by XRD alone, and confirmed its identification by XRD in NiCoAlFe-CuCr samples. The spatial distribution of phases and the grain structure in the three different samples, measured by EBSD and XEDS, is reported.
