Observation on Reaction Mechanism of Lime Powder as Desulfurization Agent for Molten Cast Iron

steel research international, Volume 96, Issue 11, Page 229-242, November 2025.
The reaction layer between lime particles and molten cast iron is comprehensively analyzed as one of the key factors in sustaining the lime‐based desulfurization process. The findings indicate the involvement of silicon, aluminum, iron, oxygen, and sulfur in a complex interplay forming specific slag systems and precipitations regulated by their ...

Analysis of acoustic emission during the melting of embedded indium particles in an aluminum matrix: a study of plastic strain accommodation during phase transformation

, 2012
Acoustic emission is used here to study melting and solidification of embedded indium particles in the size range of 0.2 to 3 um in diameter and to show that dislocation generation occurs in the aluminum matrix to accommodate a 2.5% volume change.

Enhanced Microstructural Refinement, Mechanical Performance, and Tribological Properties of Al‐9.2Si‐4.9Cu‐0.7 Mg Alloy via Friction Stir Processing

Engineering Reports, Volume 7, Issue 10, October 2025.
Friction stir processing of an Al‐9.2Si‐4.9Cu‐0.7 Mg alloy effectively refined the as‐cast coarse microstructure, reducing the average grain size from ∼5.2 μm to ∼2.6 μm and promoting a uniform redistribution of eutectic Si and intermetallic phases.

Microwave Effects on Double‐Decomposition‐Produced Hydroxyapatite: X‐ray Diffraction, Infrared Spectroscopy, Hirshfeld Surface, and Molecular Docking Studies

ChemistrySelect, Volume 10, Issue 34, September 8, 2025.
Apatitic tricalcium phosphate (Ca9(HPO4)(PO4)5(OH)) was synthesized via coprecipitation and microwave‐assisted methods. Structural (XRD), vibrational (FTIR), and thermal (TGA‐DTA) analyses confirmed phase formation. Molecular docking and Hirshfeld surface analysis revealed promising antiviral interactions with HIV‐1 targets.

Very High Cycle Fatigue Performance of Ductile Cast Iron With Different Microstructures

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 9, Page 3950-3966, September 2025.
ABSTRACT The very high cycle fatigue performance of four ductile cast irons, a solid solution strengthened ferritic, ferritic‐pearlitic, and two austempered ductile cast irons, was investigated by ultrasonic fatigue testing under fully reversed loading conditions. The step‐stress fatigue testing method incorporating re‐use of runouts was employed, with
