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.

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 ...

NAFTA’s Labour Side Agreement and International Labour Solidarity [PDF]

open access: yes, 2001
The North American Free Trade Agreement (NAFTA) and its supplemental labour pact, the North American Agreement on Labour Cooperation (NAALC), reflect the uneven advances of labour rights advocacy in connection with international trade.

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

POLICY AND PRACTICE TARGETING THE LABOUR MARKET INTEGRATION OF NON-EU NATIONALS IN IRELAND. ESRI RESEARCH SERIES NUMBER 89 JUNE 2019 [PDF]

open access: yes, 2019
Increases in immigration inflows to both the European Union (EU) and Ireland between 2014 and 2016, due in part to the ‘refugee and migrant crisis’, have resulted in an increased focus on integration policies, outcomes and measures, including in the area

Sol–Gel Derived Polymer Precursors for Stereolithography of ZrC

open access: yesAdvanced Engineering Materials, EarlyView.
ZrC is a critical material target for extreme temperature conditions. This report describes a protocol for preparing ZrC ceramics via stereolithography and examines the impact of the polymer matrix on carbothermal reduction and mechanical stability of 3D printed ZrC.

Continuous vocational education and training and new technologies: on the importance of educational level and technology in the workplace

open access: yesJournal for Labour Market Research
Continuing vocational education and training (CVET) can support technical and digital developments. At the same time, company-based training increases employability in the face of technical rationalization. Multiple studies show that the highly qualified
