Various laser scanning strategies of multitrack products, consisting a default Raster pattern (R1), with changed line order (R2), and Zigzag (Z1), different overlap rates ranged from 0.7 to 0.5, have been conducted investigate microstructure evolution for Mg-3Al-1Zn alloy. As the rate changes average grain size decreases texture is slightly concentrated, except R2 pattern. For effect pattern, relatively small can be obtained using R1, patterns compared Z1 pattern; weak The utilization results in further weakening that R1 Microstructure strategy mainly determined by low-undercooling-required epitaxial growth along temperature gradient directions at solid/liquid interface. Combined computational thermal-fluid dynamics simulation, strong fluid flow within molten pool promotes side expansion pool, resulting larger area, corresponding three-times remelting domain continuous deflections major axes.

Process parameters optimization in additive manufacturing (AM) is usually required to unlock superior properties, and this often facilitated by modeling. In electron beam powder bed fusion (E-PBF), the preheat temperature an important parameter be optimized as it significantly influences microstructure properties. Here we compare effect of two temperatures (1000 950°C, above below δ-phase solvus temperature) on microstructural evolution E-PBF IN718 Ni-based superalloy. Using thermal thermo-kinetic modeling, predict changes them with experimental findings. A decrease only 50°C has a low impact solidification slight reduction columnar grain width. solid-state, higher preheating causes intergranular precipitation, contributing γ" precipitation potential, formation co-precipitates, hardness. The lower induces intragranular reducing potential chemical composition γ' largely unaffected variation. These insights underscore importance design property control during E-PBF.
