Role of Interfacial Properties in the Evolution of Non-metallic Inclusions in Liquid Steel

ISIJ International, 2022
The evolution of non-metallic inclusions in liquid steel involves a series of processes, including nucleation, growth by diffusion and Ostwald ripening, growth by collisions, floating up and removal of relatively large inclusions, as well as pushing and ...

Modification of Non-Metallic Inclusions in Oil-Pipeline Steels by Ca-Treatment

Metals, 2019
Corrosion rate in different steel grades (including oilfield pipeline steels) is determined by the presence of non-metallic inclusions (NMI) in steels.

Non-metallic inclusions in copper and copper alloys

Journal of Materials Research and Technology
In this study, industrial copper and copper alloy samples were investigated with regard to non-metallic inclusions. Different types of inclusions (exogenous and endogenous) were detected and investigated with regard to appearance and chemical composition.

Research and Application of the Original Position Statistical Distribution Analysis Method for Non-Metallic Inclusions in P91 Steel

Metals, 2023
Heat-resistant P91 martensitic steel is used to produce high-temperature steam pipelines in (ultra) critical power plants. However, non-metallic inclusions are inevitably produced in the metallurgical process.

Effect of electroslag remelting on the non-metallic inclusions in H11 tool steel [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2018
We have studied the effect of electroslag remelting on the content and composition of non-metallic inclusions. It was found that a decrease in the non-metallic inclusion content occurred during the electroslag remelting.

Research on Intelligent Identification and Grading of Nonmetallic Inclusions in Steels Based on Deep Learning

Micromachines, 2023
Non-metallic inclusions are unavoidable defects in steel, and their type, quantity, size, and distribution have a great impact on the quality of steel. At present, non-metallic inclusions are mainly detected manually, which features high work intensity ...
