Phase diagram of chromium alloys

Using mean field theory, we have constructed the phase diagram of chromium alloys. At zero temperature, we find a first-order phase transition from the incommensurate state with manganese doping. Within a small window of manganese concentrations, a first-order phase transition from the commensurate...

Summary:Using mean field theory, we have constructed the phase diagram of chromium alloys. At zero temperature, we find a first-order phase transition from the incommensurate state with manganese doping. Within a small window of manganese concentrations, a first-order phase transition from the commensurate to the incommensurate states occurs with decreasing temperature, in agreement with experiments performed over 25 years ago on CrMn alloys.
