TL;DR: In this paper, a detailed mechanism for the formation of curved hooks and their associated periodic oscillation marks was presented, based on a careful analysis of numerous specially etched samples from ultra-low-carbon steel slabs combined with previous measurements, observations, and theoretical modeling results.

TL;DR: In this paper, the authors applied computational models and experiments with a one-third scale water model to characterize flow in the nozzle and mold to evaluate well-bottom and mountain-bottom nozzle performance.

TL;DR: In this paper, the authors focus on improving mold powders and optimizing mold oscillation and other casting conditions for high speed casting, in order to minimize break-out occurrence, and to minimize surface quality problems.

TL;DR: In this article, the authors investigated the fundamentals of meniscus solidification and how hooks form by a combination of advanced computational models and plant measurements, and they showed that hook shape is greatly affected by heat flux at the Meniscus region.

TL;DR: In this article , the potential of tailings generated from hydrometallurgical processing of nickel laterite ores as a source of scandium was investigated using an atmospheric leaching process.
