Evolution of Non-Metallic Inclusions in 27SiMn Steel

open access: yesMetals, 2022
To study the evolution of non-metallic inclusions in 27SiMn steel, the 27SiMn steel produced using the LD-LF-CCM process was sampled in various stages in a steel factory. The evolutionary behavior of inclusion in various processes was systematically analyzed by scanning electron microscopy (SEM-EDS), and the total oxygen content and nitrogen content in

Analysis of Agglomeration of Al2O3 Particles in Liquid Steel

open access: yesArchives of Metallurgy and Materials, 2016
The removal of non-metallic inclusions from liquid steel is a result of co-operation of fluctuation, adhesion and agglomeration effects, with emphasis on agglomeration which plays the most important role.

Effect of hydrogen embrittlement and non-metallic inclusions on tensile fracture properties of 55CrSi spring steel

open access: yesMaterials Research Express, 2020
The tensile fracture behavior of 55CrSi spring steels were investigated. The results demonstrate that interior inclusion and hydrogen level has a significant effect on ductility and a minimal effect on tensile strength of the spring steel.

Effect of Zr Additions on Non-Metallic Inclusions in X11CrNiMo12 Steel

open access: yesMetals, 2020
The production of clean steel is associated with high-quality steel grades for demanding applications. The formation of oxide inclusions mainly depends on the deoxidation practice; it is usually carried out through Al additions, but alumina inclusions ...
