Transmission Electron Microscopy (TEM), Atom Probe Field-Ion Microscopy (APFIM) and Small Angle Neutron Scattering (SANS) have been used to characterize the microstructure of a commercial Fe-30.1 at. % Cr-9.9 at. % Co alloy. One goal of this investigation was to demonstrate the complementary nature of these techniques in solving a difficult materials problem, the characterization of fine scale spinodally-decomposed structures. The alloy was solution treated at 925/sup 0/C for 140 min followed by water quenching, isothermal aging at 525/sup 0/C for times of 2, 8, 24, 72, 192, or 485 h and a final water quench. TEM characterizations were performed with Philips EM400T/FEG, Philips EM430T and JEM 120C instruments.
