摘要: Transmission electron microscopy was used to study grain boundary precipitation of an Fe-10Ni-7Mn (wt pct) maraging steel during isothermal aging at 753 K. Precipitation a face-centered tetragonal (fct) θ-NiMn phase in association with solute-depleted precipitate free zone (PFZ) found prior austenite boundaries. Precipitation-induced puckering boundaries the early stages initiates displacement, creating PFZs behind displaced boundary. Further migration is driven by manganese and nickel concentration gradients across migrating elastic strain energy interphase fine fct particles that be swept Consequently, coarsening occurs via diffusion as they are passed As rationale, reaction defined discontinuous precipitates, featuring nodular morphology aggregate. Continuous within facing front decreases overall driving force later stages, which leads decelerated rate.
