CALPHAD-assisted morphology control of manganese sulfide inclusions in free-cutting steels

Strategies Regarding High-Temperature Applications w.r.t Strength, Toughness, and Fatigue Life for SA508 Alloy

“…Meanwhile, the morphology of these sulfide inclusions has a significant impact on a variety of steel properties. Manganese sulfide has also harmed steel alloy mechanical properties and corrosion parameters [ 20 ]. MnS inclusions are a stress raiser with soft nature, low-shear strength, and excellent ductility such that the cutting resistance of steels and the tool wear rate are reduced.…”

Inclusions modification and improvement of machinability in a non-quenched and tempered steel with Mg treatment

“…The slender inclusions could significantly reduce the transverse impact toughness and elongation of the steel, but more short and coarse inclusions are good for the lateral mechanical properties of steel. Besides, the smaller the aspect ratio of the inclusions is, the more favorable the cutting [23]. Then 105-150 nucleation cores for the composite inclusions were detected by SEM-EDS, and the statistics for the composition of the inclusions is shown in Figure 5.…”

A multifunctional separator modified using Y2O3/Co3O4 heterostructures boosting polysulfide catalytic conversion for advanced Li–S batteries

“…Metal oxides have excellent adsorption properties due to the high polarity of metal–oxygen bonding and abundant polar active sites ( e.g. , TiO 2 , 30 Co 3 O 4 , 31 Mn 3 O 4 32 and Fe 3 O 4 33 ), especially rare earth oxides (REOs) also have definite electrocatalytic properties ( e.g. , CeO 2 , 34 Y 2 O 3 , 35 Eu 2 O 3 36 and La 2 Zr 2 O 7− x 37 ), which could accelerate the redox kinetics of the reaction process and further enhance battery performance.…”
