Factor which governs the feature of texture developed during additive manufacturing; clarified from the study on hexagonal C40-NbSi2

C40-NbSi2 with a hexagonal unit cell is focused as high-temperature structural material. We first attempted the fabrication of bulk products via selective laser melting (SLM) in additive manufacturing (AM) process. Strong crystallographic texture control wherein <0001> was parallel to building direction, i.e. development so-called basal fiber texture, achieved this study. The developed does not largely vary by changing scanning strategy, unlike textures C11b-MoSi2 tetragonal and β-Ti alloy cubic cell. A comparison these results led us conclusion that crystal symmetry, i.e., multiplicity preferential growth one primary factors governs features AM-built materials.
