Abstract Scope The design and corrosion resistance of single-phase Ni-Fe-Cr-Mo-W-X (X=Ru, Mn, Al, and Cu) MPEAs has been recently reported. In this study, these alloys were heat treated at 800 C for up to 160 h starting from the solutionized single-phase to allow precipitation of secondary phases that provide increased hardness and strength. During heat treatment at 800 C, σ-phase rich in Cr, Ru, Mo and W precipitated in each alloy. After aging, the hardness of the MPEAs containing Ru and Al showed the most significant increase in hardness, about 60 and 90 % respectively, due to the precipitation. Some of the MPEAs were found to resist localized corrosion after the aging heat treatment. While the Ru-containing MPEA was resistant to localized corrosion at temperatures up to 80 C, the ones containing Mn, Cu or Al became susceptible to localized breakdown at the interface between the matrix and precipitate at ambient temperatures.
