Abstract:In order to explore the influence of the Ti element on the microstructure and mechanical properties of high entropy alloys(HEA)

using spark plasma sintering(SPS) method synthesize CrFeCoNiTix (x=0.2

1.0) more ingredients of HEA. Using OM

XRD and SEM techniques to explore the microstructure of the alloy

and tested the hardness

compression strength and corrosion resistance. Research has shown that the high entropy of different content of Ti alloy have the simple organization form

face centered cubic is the main solid solution phase. With increasing Ti content

the hardness of HEA increases and the maximum hardness is 672.59HV; High entropy alloys compression strength also increases

the maximum value is 690.28MPa. The corrosion resistance of HEA decreased with increasing Ti content in H2SO4.
