Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Sandwich-Type Results and Existence Results of Analytic Functions Associated with the Fractional q-Calculus Operator

Fractal and Fractional
In the present investigation, we present certain subordination and superordination results for the q-integral operator of a fractional order associated with analytic functions in the open unit disk U.

Multilinear Fractional Integral Operators with Generalized Kernels

Taiwanese Journal of Mathematics
In this article, we introduce a class of multilinear fractional integral operators with generalized kernels that are weaker than the Dini kernel condition. We establish the boundedness of multilinear fractional integral operators with generalized kernels on weighted Lebesgue spaces and variable exponent Lebesgue spaces, as well as the boundedness of ...

Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

Advanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

On the Behaviors of Rough Fractional Type Sublinear Operators on Vanishing Generalized Weighted Morrey Spaces

International Journal of Analysis and Applications, 2019
The aim of this paper is to get the boundedness of rough sublinear operators generated by fractional integral operators on vanishing generalized weighted Morrey spaces under generic size conditions which are satisfied by most of the operators in harmonic

Estimates of Fractional Integral Operators on Variable Exponent Lebesgue Spaces

Journal of Function Spaces, 2016
By some estimates for the variable fractional maximal operator, the authors prove that the fractional integral operator is bounded and satisfies the weak-type inequality on variable exponent Lebesgue spaces.

CHOQUET INTEGRALS, HAUSDORFF CONTENT AND FRACTIONAL OPERATORS

Bulletin of the Australian Mathematical Society
AbstractWe show that the fractional integral operator $I_{\alpha }$ , $0<\alpha <n$ , and the fractional maximal operator $M_{\alpha }$ , $0\le \alpha <n$ , are bounded on weak Choquet spaces with respect to Hausdorff content. We also investigate these operators on Choquet–Morrey spaces. The results for the fractional maximal operator $M_\

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

EBSD Study of Creep‐Induced Lattice Misorientation in MgO‐Particle‐Reinforced Austenitic Steel Composites

Advanced Engineering Materials, EarlyView.
Creep experiments at 900°C on coarse‐grained steel‐ceramic composites containing recycled magnesia reveal that higher ceramic volume fractions significantly enhance the creep resistance. Detailed EBSD investigations identify subgrain formation in the steel matrix as the dominant deformation mechanism.

Weighted inequalities for multilinear fractional integral operators

Collectanea mathematica, 2009
The author considers fractional multilinear integral operators \[ {\mathcal I}_\alpha \vec{f}(x):= \int_{\left({\mathbb R}^n\right)^m } {f_1(y_1) \cdots f_m(y_m)\over \left(|x-y_1|+\dots+|x-y_m|\right)^{nm-\alpha}} d\vec{y}. \] Sufficient conditions for the two weight inequalities \[ \left(\int_{{\mathbb R}^n} (|{\mathcal I}_\alpha\vec{f}|u)^q dx\right)
