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

open access: yesAdvanced 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.

Structural performance of composite beams: effects of continuity and slenderness ratio

open access: yesJournal of Engineering and Applied Science
An experimental study was conducted to investigate the performance of both simply supported and continuous steel beams acting compositely with reinforced concrete slabs using profiled steel sheeting and shear connectors.

Double-lambda microscopic model for entangled light generation by four-wave-mixing [PDF]

open access: yes, 2010
Motivated by recent experiments, we study four-wave-mixing in an atomic double-{\Lambda} system driven by a far-detuned pump. Using the Heisenberg-Langevin formalism, and based on the microscopic properties of the medium, we calculate the classical and ...

Moment redistribution in cold-formed steel continuous beams

open access: yes, 2016
The external envelope of steel framed industrial buildings normally involves the use of purlins and rails spanning between the main hot-rolled frames to support the roofing/cladding.

Reduction of Oxide Inclusions During the High‐Frequency Welding of Steel via a Nonthermal Ar/H2 Plasma Jet

open access: yesAdvanced Engineering Materials, EarlyView.
High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Continuous axial scanning of a Gaussian beam via beam steering

open access: yesOptics Express, 2017
We propose and demonstrate experimentally the transfer of one spatial degree of freedom of a laser beam onto another one. Using a multi-plane light conversion device (MPLC) and a modal analysis, we designed a passive setup with immediate response which couples a displacement and tilt in the transverse plane to a longitudinal shift of the focus point of
