Synergistically enhanced cryogenic strength and ductility in 304L stainless steel made by directed energy deposition additive manufacturing by Yen-Ting Chang, Andrew Hattoon Enriquez, Yuheng Nie, Didun Oladeji, Marie A. Charpagne

“…We find that regardless of the printing strategy, DED AM 304L exhibits synergistically enhanced strength and ductility from room temperature down to cryogenic temperature (77 K); that surpasses the mechanical performance of 304L synthesized via conventional processes. We follow the evolution of statistically representative microstructure regions using electron microscopy during quasi in-situ tensile tests interrupted at different strain levels and reveal the deformation mechanisms responsible for this behavior. …”

Monolithic conversion of AZ31 Mg alloy plates to struvite in saturated ammonium dihydrogen phosphate solutions by Erdem Şahin, Meltem Alp, Ahmed Şeref

“…Close examination of the cross section by SEM revealed formation of mainly prismatic crystals of struvite perpendicular to the rolling direction of the plates, thus intercalating and simultaneously densifying the microstructure. However such long term struvite growth could not be sustained in any of the studied multicomponent solutions of ADP, which highlights the unique pH evolution of saturated ADP solution that is suitable for continuous struvite formation. …”
