heal.abstract	The cooling rate of a duplex stainless steel from high temperature (region of stability of alpha-ferrite) down to the ambient temperature is critical for the mutual formation of its constituent phases, i.e. ferrite and austenite, and for their content in alloying elements. Therefore it is expected that cooling rates will affect indirectly the transformation and precipitation phenomena occuring during subsequent heat treatment. The aim of this study is to investigate the influence of the cooling rate on the transformation behavior of a SAF 2205 duplex stainless steel subjected to heat treatments in the temperature range between 500 degrees C to 800 degrees C. The specimens were solution annealed at 1100 degrees C and then cooled in air, oil or water. They were subsequently subjected to isothermal heat treatment for 5 hours at temperatures of 500, 600, 700 and 800 degrees C. The structural evolution was investigated using several techniques, among them optical, scanning and transmission electron microscopy coupled with extensive EDS X-ray microanalysis and selected area electron diffraction pattern analysis.	en
