Also, for the studied ranges, the microstructure texture is not related to the powder layer thickness or to the laser emission mode, although it could be affected by the laser power or the scan strategy. Results show that the heat treatment intrinsic to the LPBF process does not affect the prior austenite grains, whose texture and morphology remain unchanged throughout the process. To do so, X-Ray Diffraction, Electron Backscattered Diffraction and Scanning Electron Microscopy have been used. different printer, powder layer thickness and laser emission mode. ![]() ![]() This work aims to investigate these findings by using a 300 maraging steel processed under different conditions, i.e. ![]() Authors suggested several hypotheses, although no conclusions were drawn. A recent publication showed a low texture index in the prior austenite, in contrast to other alloys subjected to LPBF with the same strategy. ![]() However, the effects of the processing parameters and the mechanisms governing the as-built texture are not clear yet. Among the materials that might be manufactured with laser powder bed fusion (LPBF), one can highlight maraging steels, with excellent weldability, strength and fracture toughness. ![]()
