Figure 2. Microstructures and mechanical properties in AM. (A) Microstructure of a melt pool, equiaxed at the periphery and dendritic along the solidification direction [89]. (B) Spiral microstructure pattern observed due to 67 degree layer rotation scanning strategy [95]. (C) Lamellar grains comprised of alternating
