The Fe40Mn28Ni32-xCrx (x=0, 4, 8, 12, 18, 24 (at.%)) high entropy alloys were prepared by vacuum arc melting. The alloys with x≤18 were ductile single phase fcc solid solutions. The Fe40Mn28Ni8Cr24 alloy had brittle intermetallic sigma phase matrix after homogenization. Mechanical properties of the solid solution alloys were studied in recrystallized condition. It was demonstrated that tensile yield strength increases with increase of Cr content, but ductility decreases. Yield strength of solid solution alloys was compared with predicted solid solution strengthening and good correlation has been found. Microstructure evolution in the solid solution alloys during plastic straining was studied. Effect of Cr content on phase composition and deformation behavior of the alloys is analyzed.
