摘要：
The current study examines the impact behavior of thermomechanically processed Fe-6.78Mn-3.92Al-0.18C (wt. %) steel after intercritical annealing at 700, 750 and 800 degrees C. The formation of a multi-phase microstructure with blocky and lath-type reverted austenite (RA)/martensite (M), fine intercritical ferrite (IF), and coarse elongated ferrite (EF) is revealed by electron backscatter diffraction (EBSD). When subjected to the Charpy-impact test, the sample annealed at 750 degrees C shows the highest impact energy owing to high transformation-induced-plasticity (TRIP) effect. To further comprehend the micro-mechanism of fracture, the fracture surface is also examined by scanning electron microscopy (SEM).
