high performance alloys for resistance to aqueous corrosion
Aqueous Corrosion Behavior of Cast CoCrFeMnNi Alloy
CoCrFeMnNi high-entropy alloy demonstrates good mechanical properties and can be further strengthened by thermomechanical processes. A sample alloy prepared by vacuum casting in a graphite mold was further investigated for its corrosion resistance. One-millimeter thin strips of cast alloy were used to investigate its corrosion behavior at room temperature.
