Non-metallic inclusions in aluminium killed steels

Ironmaking & Steelmaking, 2002
AbstractHeats of medium carbon aluminium killed, low carbon silicon-aluminium killed, and low carbon aluminium killed steels were sampled with short time intervals during ladle metallurgy. Non-metallic inclusions were extracted from the steel matrix and investigated using scanning electron microscopy and energy dispersive spectrometry.

Autoradiographic Investigations of Endogenic Non-Metallic Inclusions

Isotopenpraxis Isotopes in Environmental and Health Studies, 1987
The quantitative autoradiography of “point” sources, i.e. the sources of diameters between 5 … 100 μm, has enabled investigations of insulated non-metallic inclusions. Several heats were made in an induction furnace. ST-5 steel samples were deoxidated by use of complex deoxidizers Al + Ce contained various amounts of cerium with the radioisotopes 141 ...

Advancing Analysis of Non-Metallic Inclusion Datasets

2022
Non-metallic inclusions play a major role in defining the properties of steel and their examination has been greatly aided by automated scanning electron microscopes (SEM) coupled with energy dispersive x-ray spectroscopy (EDS). The output of SEM/EDS analysis generates a great deal of data that has not been utilized. The current work exploits this data

Surface modelling of crystalline non-metallic inclusions

Journal of Non-Crystalline Solids, 2001
Abstract Non-metallic inclusions such as corundum and spinel-type compounds are crystalline at steelmaking temperatures. The crystal structure and the configuration of the atoms at the crystal surfaces affect the surface related energies and thus the growth forms of the inclusions near equilibrium.

Microstructure, non-metallic inclusions and impact toughness of high-Mn cryogenic steel weld metal

Science and technology of welding and joining, 2022
Microstructure, inclusions and cryogenic impact toughness of Fe-22.03Mn-0.45C austenitic weld metal were investigated. The results show that microstructure of weld metal consisted of straight columnar dendrites with different orientations ...

Effect of Al content on non-metallic inclusions in Fe–23Mn–xAl–0.7C lightweight steels

Ironmaking & steelmaking, 2021
The composition, morphology, number, area, size and average distance of inclusions in Fe–23Mn–xAl–0.7C steels were evaluated through an inclusion automatic analysis system (INCA Feature).

Non-metallic inclusion entrapment by slags: laboratory investigation

Ironmaking & Steelmaking, 2003
AbstractNon-metallic inclusions that originate from secondary metallurgy treatments may provoke nozzle clogging during continuous casting and lead more or less directly to surface defects on final products. The amount of these non-metallic inclusions (oxides or nitride) in the solid or liquid steel is governed by the steelmaking practice and in ...
