IMPACT OF CAST SPEED ON THE OCCURRENCE OF THE NON-METALLIC INCLUSIONS IN STEEL

Acta Metallurgica Slovaca, 2016
This paper deals with the examination of the impact of steel cast speed on the occurrence of the non-metallic inclusions due to the investigation of the individual samples taken at different steel cast speeds.

The effects of non-metallic inclusions on properties relevant to the performance of steel in structural and mechanical applications

Journal of Materials Research and Technology, 2019
Non-metallic inclusions (NMIs) occur typically in low or very low volume fractions (from 10−2 in a high oxygen weld deposit to 10−5 in very clean bearing steels) but play an important role in many properties of steel.

Influence of Non-Metallic Inclusions on Very High-Cycle Fatigue Performance of High-Strength Steels and Interpretation via Crystal Plasticity Finite Element Method

Metals
The fatigue behaviors of high-strength bearing steel were investigated with rotating bending fatigue loading with a frequency of 52.5 Hz. It was revealed that the high-strength steel tended to initiate at interior non-metallic inclusions in a very high ...

Evaluation of different alloying concepts to trace non-metallic inclusions by adding rare earths on a laboratory scale

Ironmaking & Steelmaking, 2022
Different alloying concepts to trace deoxidation products, mainly aluminium oxides, using rare earth elements (REEs), were tested on the laboratory scale by melting trials with a high-frequency remelting furnace. Lanthanum and Cerium, which belong to the
