Figure 6. Graphical workflow of the multi-step heat-treatment strategy and the associated microstructure-property relationship: (A) Temperature-time profile for the investigated processing route (480 °C/3 h + 600 °C/1 h); (B-D) Schematic microstructural evolution from the as-printed cellular template through precipitation to intercritical austenite reversion, forming an interconnected austenite network; (E) Stacked bar chart of austenite fraction normalized by the initial austenite fraction (γ/γ₀) across engineering strain intervals. Values are shown for major contributors, minor bins (< 5%) are unlabeled for clarity. AM: Additive manufacturing.
