Abstract
Retained austenite particles with nanometric dimensions in 9 % nickel steel s microstructures were observed after differents intercritical tempering tr eatments ranged between 540 degrees C and 670 degrees C corresponding to th e (alpha + gamma) two-phase field of Fe-Ni diagram. The thermal stability o f particles turned out to be strongly influenced by its nickel contents and gradients of this element. The gradients were dependent on time and temper ature of tempering.
