“…Composite material is a combination of two materials with different characters to obtain new materials with superior properties, ceramic phases were widely used due to their high melting point and high hardness in traditional alloys [17][18][19][20][21][22][23]. Due to the excellent properties of HEAs, some scholars investigated the effect of ceramic phases on high entropy alloys.…”

To enhance the strength of single FCC phase high entropy alloys, TiC was selected as reinforced phase to improve the properties of high entropy alloys (HEAs). Therefore, a series of TiC/Al 0.6 CrFe 2 Ni 2 high entropy alloys with different TiC content which ranging from 0 to 5 vol% were prepared by vacuum arc melting furnace. The phase compositions, microstructures and mechanical properties of alloys were investigated detailedly. The results show that TiC has no effect on phase composition of the alloys, but the addition of ceramic phase TiC has an advantageous effect on the mechanical properties of alloys, the yield strength of TiC/Al 0.6 CrFe 2 Ni 2 HEAs increases due to the refined of grain size, when TiC content is 2.50 vol%, alloy has better properties, the yield strength and Vickers hardness are 576.93 MPa and 244 HV, respectively.
