Deformation and fracture of non-metallic inclusions in steel at different temperatures

Journal of Materials Research and Technology, 2020
Experiments were carried out to investigate the deformation and fracture of non-metallic inclusions in steel at different temperatures. The deformation of inclusions at high temperature could be characterized by viscosity.

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.

Effect of ferrochromium (FeCr) and ferroniobium (FeNb) alloys on inclusion and precipitate characteristics in austenitic stainless steels

Journal of Materials Research and Technology, 2023
Lab-scale alloying experiments were carried out by first adding commercial low-carbon ferrochrome (LCFeCr) alloys and then adding ferroniobium (FeNb) alloys in 316-grade austenitic stainless steel in this study.

Comparison of the Internal Fatigue Crack Initiation and Propagation Behavior of a Quenched and Tempered Steel with and without a Thermomechanical Treatment

Metals, 2022
Previous studies have shown that a thermomechanical treatment (TMT) consisting of cyclic plastic deformation in the temperature range of dynamic strain aging can increase the fatigue limit of quenched and tempered steels by strengthening the ...

The Effect of Different Non-Metallic Inclusions on the Machinability of Steels [PDF]

Materials, 2015
Considerable research has been conducted over recent decades on the role of non‑metallic inclusions and their link to the machinability of different steels. The present work reviews the mechanisms of steel fractures during different mechanical machining operations and the behavior of various non-metallic inclusions in a cutting zone. More specifically,
