Austenite reversion in cold formed 18 wt-%Ni 350 grade maraging steel

Abstract

Austenite reversion as a function of deformation processes has been investigated in an 18 wt-%Ni 350 grade maraging steel. The results reported show that the degree and type of deformation imparted to martensite influences the amount of reverted austenite obtained following aging. The validity of the X-ray diffraction technique in determining the reverted austenite content is discussed with reference to texture incorporated during cold forming. Transmission electron microscopy was carried out to study the partitioning of solute during austenite reversion.
