The stacking-fault energies of commercial austenitic alloys were determined using X-ray diffraction line profile analysis (table 2). 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. Regression analysis of the data gave an expression which related the energy to commercial alloy compositions in terms of the Ni, Cr, Mn and Mo concentrations.
