Figure 4. EBSD parent grain reconstructed IPF map, HCP ε-martensite IPF map, and the grain size distribution of Fe-30Mn-6Si LPBF-built alloy from LED of (A-C) 0.25 J/mm (100 W, 400 mm/s), (D-F) 0.29 J/mm (175 W, 600 mm/s), (G-I) 0.44 J/mm (175 W, 400 mm/s), and (J-L) 0.88 J/mm (175 W, 400 mm/s, and 100% re-scan), respectively, and the IPF colour key for (M) FCC and (N) HCP. The build direction is from right to left and the grain boundaries are outlined in black.
