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

open access: yesEngineering 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

open access: yesChemistrySelect, 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.

A metallography and x-ray tomography study of spall damage in ultrapure Al

open access: yes, 2014
We characterize spall damage in shock-recovered ultrapure Al with metallography and x-ray tomography. The measured damage profiles in ultrapure Al induced by planar impact at different shock strengths, can be described with a Gaussian function, and ...

Effect of Solution Temperature on the Microstructure of 18%Ni Maraging Steel Modified With Nb—X‐Ray Diffraction and Electron Backscattered Scanning Diffraction (EBSD) Analyzes

open access: yesX-Ray Spectrometry, Volume 54, Issue 5, Page 547-555, September/October 2025.
ABSTRACT Maraging steels are high strength alloys used in applications that require both high mechanical strength and toughness. To achieve these properties, one of the heat treatments applied is solution treatment, although it can reduce toughness.
