Abstract

The effect of Ti/Al ratio on the elemental partitioning in the Ni₂CoFeCrTi_xAl_y high entropy alloy was studied by atom probe tomography (APT). The APT results indicate that the γ′ nanoparticles have a composition of (NiCoFeCr)₃TiAl which is independent of Ti/Al ratio. The effect of Ti/Al ratio on the partitioning behaviors of Fe and Cr are significantly different from that of Co. The decreasing of Ti/Al ratio significantly enhanced the incorporation of Fe and Cr into the γ′ nanoparticles. However, the concentration of Co in the γ′ nanoparticles declined with the decrease of Ti/Al ratio.
