TY - JOUR ID - 564827 AU - Svoboda, Milan - Kroupa, Aleš - Sopoušek, Jiří - Vřešťál, Jan - Miodownik, Peter PY - 2004 TI - Phase changes in superaustenitic steels after long-term annealing JF - Zeitschrift fur Metallkunde VL - 95 IS - 11 SP - 1025-1030 EP - 1025-1030 PB - Carl Hanser Verlag SN - 00443093 KW - Austenitic steels KW - Microstructure KW - Thermodynamic modelling KW - Calphad method N2 - A structural study was performed on the austenitic steels Avesta 254 SMO and Avesta 654 SMO after annealing at 700 C for 500, 3188 and 6170 h. Both Avesta steels initially show an unexpectedly large amount of the Laves phase, followed by a relative slow development of the Sigma phase with equilibrium apparently not yet reached after 3188 h. Thermodynamic calculations confirm that the driving forces for alternative precipitates are very similar thus making it easy to form metastable precipitates that only change very slowly to the equilibrium state. TTT calculations also comnfirm that the Laves phase precipitates earlier than the Sigma phase as the temperature is lowered. ER -
