Abstract

Retained austenite particles with nanometric dimensions in 9 % nickel steels microstructures were observed after different intercritical tempering treatments ranged between 540 °C and 670 °C corresponding to the (α + γ) two-phase field of Fe-Ni diagram. The thermal stability of particles turned out to be strongly influenced by its nickel contents and gradients of this element. The gradients were dependent on time and temperature of tempering.
