Quantifying MnS Inclusion Evolution Behaviors During 1473 K Heating in EH36 Shipbuilding Steel with Zr Addition

In Situ Observation on the Heterogeneous Nucleation of MnS in Heavy Rail Steels with Varied Aluminum Content

“…[4][5][6][7][8] Particularly, large and long MnS inclusions precipitated during heat treatment after rolling of the steel and have a detrimental effect on the strength and corrosion resistance of heavy rail steels. [9][10][11][12][13] Many studies were reported to control large-sized MnS inclusions according to the characteristic and source of MnS in the steel, such as slag refining, [14,15] calcium/magnesium addition, [16][17][18][19] zirconium/cerium addition, [20][21][22] heat treatment process, [23,24] and heterogeneous nucleation improvement. [25][26][27] Oikawa et al [28,29] studied the effect of Ti addition on the formation and distribution of MnS inclusions in Fe-0.1%C-1%Mn-0.02%S steels during solidification.…”

Effect of Magnesium Treatment and Cooling Method on Manganese Sulfide in U75V Heavy‐Rail Steel Deoxidized by Si–Mn

“…Furthermore, this inclusion exhibits less deformation during hot processing, and the steel has good cutting performance; thus, the transverse mechanical properties of the steel are less affected. Therefore, controlling the size, shape, quantity, and distribution of MnS inclusions in steels is important.Currently, the control of MnS is primarily divided into four types: 1) adding strong deoxidizing elements such as Ti, [6][7][8][9] Mg, [10,12] and Zr [13][14][15] to molten steel. Several fine oxides are formed in the molten steel, which can function as the nucleation core of MnS.…”
