The stacking-fault energies of commercial austenitic alloys were determined using X-ray diffraction line profile analysis. From a comparison with existing data on laboratory alloys having similar compositions, it was concluded that both Ni and C increased the energy while Cr, Si, Mn and N decreased it. The stacking-fault energies of Fe-21Cr-6Ni-9wt%Mn and Fe-22Cr-13Ni-5wt%Mn were 53 and 64mJ/m2, respectively.
