Popis | Anticorrosion superaustenitic steels reach first equilibrium concerning carbon atoms at higher temperatures (paraequilibrium). Later on, true thermodynamic equilibrium is accomplished after diffusion of substitutional atoms (ortoequilibrium). Later step influences the longevity of materials in exploitation conditions. The structural study was performed on austenitic anticorrosion steels NICROFER 3033 and Avesta 254 SMO after annealing 700 C/500 hrs. |
