Mechanical and Metallurgical Evaluation of Four Rotary Nickel‐Titanium File Systems: A Multimethod Study

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Aim To compare four rotary nickel‐titanium (NiTi) file systems (Endostar E3 Azure, Endostar E3, VDW.ROTATE, and Mtwo) using a multimethod approach to evaluate their mechanical and metallurgical properties. Materials and Methods Endostar E3 Azure, Endostar E3, VDW.ROTATE, and Mtwo (all size 25/0.06 with an S‐shaped cross‐section; 52 instruments

Nanoprecipitate characterisation in NiTi and aluminium alloys: A TEM‐based overview

open access: yesJournal of Microscopy, EarlyView.
Abstract Nanoscale precipitates are central to the functional and mechanical performance of many advanced alloys, yet their characteristics and spatial distributions can be directly resolved only by electron microscopy. In this poster‐style article, focused ion beam‐prepared TEM lamellae are used to provide a microscopy‐focused overview of ...

Evidence of a local BCC‐type coordination of cobalt in FCC taenite of iron meteorites

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Ni, Co, and Fe K‐edge X‐ray absorption fine structure (XAFS) measurements were performed, revealing an unexpected local structure around Co in well‐known iron and stony‐iron meteorites. Cobalt is enriched in kamacite but remains in taenite at concentrations of at least 0.3 atom%.

On the Lightweight Potential of Laser Additive Manufactured NiTi Triply Periodic Minimal Sheet Lattices

open access: yesAdvanced Engineering Materials, Volume 28, Issue 15, 5 August 2026.
This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.

Abnormal Phase Transition Mechanism in the CoCrAlY Bond Coat Revealed by In Situ and Ex Situ Experiments

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT In Co‐based alloys, the γ phase is normally stable at high temperatures and the ε phase at low temperatures, and there is a martensitic transition on cooling to ∼417°C. In the γ/β dual‐phase CoCrAlY bond coat of turbine blade thermal barrier coating systems, we observed the opposite: γ remained stable at room temperature, yet it underwent a γ →
