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.

Effect of nonmetallic inclusions on steel welds metal hot cracking
Intercrystally distributed nonmetallic inclusions greatly increase weld susceptibility to hot cracking. Oxide and sulphide inclusions are the result of contaminated base material or its highly oxidised surfaces and they can be a consequence of ...

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 ...
