摘要
The microstructural changes in a 0.05C-26.3Mn-4.88Si-4.13Al-Fe alloy were studied. The two constituting phases were austenite and ordered DO3. The morphology of austenite phase was found to be different under various conditions. The DO3 phase had a modulated microstructure, and secondary austenite flakes precipitated within the DO3 matrix when both cast and hot-rolled alloys were heat treated at 1073 K (800 A degrees C). An attempt was made to explain the secondary austenite precipitation in view of a schematic phase diagram.
