Abstract
A commercial duplex stainless steel has been aged at 673 K for up to 55,000 h. The aging results in the phase decomposition of the ferrite in duplex stainless steel. The end products of the phase decomposition are a Fe-rich and a Cr-rich phase. The chromium concentration of these phases is determined by measuring the hyperfine magnetic field and the isomer shift using Mössbauer effect. The experimental results are compared with a phase diagram calculated for Fe–Cr–Ni ternary system at 673 K.
