Evaluation and Analysis of the Influence of Rare-Earth Ce on Inclusions in Heavy Rail Steel
Metals, 2023 The effect of rare-earth Ce on the evolution behaviour of inclusions in heavy rail steel was studied. The addition of Ce can significantly reduce the number and size of class A, B, D, and Ds inclusions in the heavy rail steel smelting process.

On the automated characterisation of inclusion-induced damage in 16MnCrS5 case-hardening steel
Advances in Industrial and Manufacturing Engineering, 2023 Manganese sulphide inclusions are commonly found in steels and known to facilitate the formation of deformation-induced damage sites in the form of voids during cold forming. These damage sites either exist as cracks, splitting the inclusion in two parts,
