Microalloying is an effective approach to improve the macroscopic properties of alloys. For understanding the microalloying effect on the dynamic behavior of metallic glass-forming systems, the impact of alloying the metalloid-like element Al on the melt viscosity of the Zr 72-x Co 28 Al x (x = 4,8,16,24) alloys has been investigated utilizing the electrostatic levitation …

Global steel production is a unique opportunity for far-reaching decarbonization initiatives (Lei et al. 2023).To turn iron into steel, three energy-intensive steps occur: (a) reducing iron oxide to metallic iron at a high temperature with chemical reductors (e.g., carbon, hydrogen and methane, pure or mixed); (b) melting the metallic iron at high temperature and removing …

This included crushing the samples to passing 2 mm (unprocessed ore) and splitting into 1 kg aliquots. Milling curves were constructed [53]. Three target grind sizes were selected for this study. The target grind employed at the mine (i.e., P80 of 75 µm), was selected for comparison along with a coarser and finer grind relative to this.

Quantitative comparisons suggest that this poisoning action cannot be attributed solely to reduction in growth restriction arising from changed solute contents in the melt. Microscopic …
