Thermodynamic Constraints and Prospects for Intensified Steel Deoxidation
The article provides a short survey of steel deoxidation and considers how to increase its efficacy. Bringing a specially tailored, powdered slag into the reaction site can directly bind the deoxidation product oxides, resulting in lower dissolved oxygen activity, total oxygen content, and cleaner steel.

Phosphorus Partition in an Industrial Basic Oxygen Furnace Process in Ukraine
Phosphorus partition data from Ukrainian steel plants are analyzed, focusing on parameters like basicity, optical basicity, tapping temperature, and slag contents of FeO, MgO, and Al2O3. The analysis shows that phosphorus partition decreases with higher tapping temperatures and increases with optical basicity.

Abstract Correlation of ignimbrite units at polygenic calderas is mandatory for the reconstruction of caldera‐forming events and proper identification of their eruption dynamics. However, ignimbrites erupted at different times from the same caldera can display similarities in composition and lithology that can hamper proper correlation of outcrops ...

This perspective article explores an innovative powder metallurgical approach to producing high‐nitrogen steels by utilizing a mixture of stainless steel and Si3N4. This mixture undergoes hot isostatic pressing followed by direct quenching. The article also examines adapting this method to laser powder bed fusion (PBF‐LB/M) to overcome nitrogen ...
