In this work, a blend of Ti, Nb, and Mn powders, with a nominal composition of 15 wt.% of Mn, and balanced Ti and Nb wt.%, was selected to be mechanically alloyed by the following two alternative high-energy milling devices: a vibratory 8000D mixer/mill® and a PM400 Retsch® planetary ball mill. Two ball-to-powder ratio (BPR) conditions (10:1 and 20:1) were applied, to study the evolution of the synthesized phases under each of the two mechanical alloying conditions. The main findings observed include the following: (1) the sequence conversion evolved from raw elements to a transitory bcc-TiNbMn alloy, and subsequently to an fcc-TiNb15Mn alloy, independent of the milling conditions; (2) the total full conversion to the fcc-TiNb15Mn alloy was only reached by the planetary mill at a minimum of 12 h of milling time, for either of the BPR employed; (3) the planetary mill produced a non-negligible Fe contamination from the milling media, when the highest BPR and milling time were applied; and (4) the final fcc-TiNb15Mn alloy synthesized presents a nanocrystalline nature and a partial degree of amorphization.

Prof. J.A. PeñaRanier Enrique Sepúlveda FerrerIron oxide scaffolds with gradient porosity were fabricated using the freeze-casting technique. Doped iron oxide particles were employed to generate stable particle suspensions in camphene using the ball-milling technique. Viscosity measurements were performed to determine the effect of the milling time and the additive incorporation. The freeze-casting process implemented in this work created a wide diversity of solidification front velocities, [ ] (2–80 µm s−1), and thermal gradients,[ ] (0.2–20°C cm−1) during sample fabrication. The solidification problem of liquid/solid systems has often been reviewed, but usually only under steady-state conditions. This study presents a much simpler approach for the correlation of the average dendrite arm spacing [ ] and pore morphology with different processing parameters. GRAPHICAL ABSTRACT

Dr. Pedro Javier Lloreda-Jurado holds a degree in Industrial Chemical Engineering from the University of Jaén (Spain, 2015), specializing in environment and materials. In 2022, he completed his PhD in Science and Technology of New Materials, with an International Mention. Throughout his doctoral studies, he conducted research stays at Northwestern University (USA, 2019) and the Institute of Ceramic and Glass—CSIC (Spain, 2021), gaining valuable international exposure. From 2022 to 2023, Dr. Lloreda served as a postdoctoral researcher at the Institute of Materials Science of Seville—CSIC (Spain), specializing in optical characterization and thin-film synthesis via magnetron sputtering. He teaches and conducts research at the University of Seville, focusing on nanomaterials for sustainable energy applications, including green hydrogen generation and storage. Using powder metallurgy techniques, such as nanoparticle synthesis, ball-milling, and freeze-casting, he develops porous materials with enhanced efficiency and durability. His research has led to influential publications in high-impact journals, contributing to advancements in doped porous foams, stable dispersions, and the rheological, mechanical, and chemical properties of materials.
