Abstract
Utilizing high resolution transmission electron microscopy (HRTEM) and X-ray diffraction (XRD), chemical composition characteristics and thermal stability of reverted Austenite (RA) in 9%Ni steel processed by quench-lamellarize-temper (QLT) heat-treatment has been investigated. The results showed that Austenite-stabilizing elements, such as Ni, Mn, are inclined to concentrate in reverted Austenite and distribute unevenly in it, higher near the boundary as high as 21% and lower in the centre. It was also found that RA has good heat and mechanical stability in 9%Ni steel but likely loses its stability and transform to Martensite undergoing both ultra low temperature and mechanical loading, accordingly inducing plasticity unceasingly.
