Abstract
Prominent δ-ferrite to γ-austenite transition in the coarse-grained heat-affected zone of P92 steel has been documented in situ by confocal scanning laser microscope under different thermal cycles, with emphasis on the quantifying of migration of the γ/δ interface. With reducing cooling rate, the fraction of retained δ-ferrite decreases appreciably from 12.0 to 1.6 pct. It is further quantified that the average migration distance of γ/δ interface is enhanced from 10.74 to 17.81 μm.
