The diffusion of 51Cr in the face-centered cubic phases of this alloy system was studied by using radioactive tracer techniques at 950 to 1200C. The results could be described by:

0.93at%Cr:     D (cm2/s) = 1.30 x 100 exp[-286.0(kJ/mol)/RT]

3.31at%Cr:     D (cm2/s) = 3.50 x 10-1 exp[-273.8(kJ/mol)/RT]

7.20at%Cr:     D (cm2/s) = 1.30 x 10-1 exp[-261.6(kJ/mol)/RT]
