TL;DR: In this paper, the effect of different heat treatments and hot isostatic pressing on the microstructure and mechanical properties of laser powder bed fusion IN625 alloy was studied using optical and scanning electron microscopy.

TL;DR: Inconel 625 alloy tensile specimens fabricated by laser powder-bed fusion and subjected to different post-processing treatments, such as stress relief annealing, low-temperature solution treatment and hot isostatic pressing, were tested at room temperature and at 760°C as mentioned in this paper.

TL;DR: In this article, a simplified analytical model of the laser powder bed fusion (LPBF) process was used to develop a novel density prediction approach that can be adapted for any given powder feedstock and LPBF system.

TL;DR: In this article, the laser powder bed fusion parameters were determined for a novel biomedical Ti-18Zr-14Nb (at%) alloy using both analytical and experimental approaches, and a technological processing window corresponding to a 25-45 ǫ/mm3 energy density range and a 10-25 Ǫ/h build rate range was recommended for the fabrication of the fully dense Ti- 18Zr 14Nb alloy with improved surface roughness.

TL;DR: In this article, the laser powder bed fusion (L-PBF) technology was adapted for use with non-spherical low-cost water-atomized iron powders, and a simplified numerical and experimental modeling approach was applied to determine the operation window for the selected powder in terms of laser power, scanning speed, hatching space, and layer thickness.
