Role of Si Alloying in the Microstructure Evolution and Corrosion Performance of ZnAlMg Coatings

Materials and Corrosion, EarlyView.
Si alloying refines the coating microstructure and enables formation of Mg2Si. When present at the surface, this phase is the strongest early source of Mg2+, providing short‐term protection, followed by dissolution of MgZn2 and Zn and formation of more stable corrosion products.

Bond between galvanized steel and concrete prepared with limestone aggregates

, 2010
PurposeThe purpose of this paper is to elucidate if there is a loss in bond strength between galvanized steel used as reinforcement, and concrete of water‐to‐cement (w/c) ratio of 0.4 and 0.5, after both types of sample were cured for seven, 21 and 28 ...

Wind tunnel test study on the erosion wear of galvanized coatings on steel members under wind-blown-sand two-phase flow

Case Studies in Construction Materials
Pieces of galvanized steel angle, steel tube, and steel plate were made into test specimens, and then a uniform wind-sand flow field was formed in a reflux wind tunnel to simulate the environment of strong wind-sand areas. Through the wind tunnel testing,

Application of Circular Economy Principles to Power Generation: Extending the Life of A Hydropower Plant by Pumped Hydro Energy Storage

Sustainable Development, EarlyView.
ABSTRACT The application of circular economy, which aims to maximize efficiency and reduce waste, to renewable energy sources necessitates, given the intermittent nature of the latter, robust energy storage solutions to ensure grid stability and avoid wasting energy.

Effect of Double Annealing on the Microstructure and Mechanical Properties of a Medium Manganese Steel

steel research international, EarlyView.
A double intercritical annealing strategy is proposed to tailor the multiphase microstructure and mechanical response of a medium‐Mn steel. The treatment produces an ultrafine mixture of ferrite, martensite and multiple austenite populations with graded thermal and mechanical stability, formed through austenite reversion and controlled retransformation.

Strengthening of punching shear of flat slab–column connections through hybrid near‐surface mounted and externally bonded systems: Experimental, numerical, and analytical study

Structural Concrete, EarlyView.
Abstract Slab–column connections are vulnerable to punching shear, particularly when flexural cracking reduces the effective depth. This study proposes a sustainable dual‐strengthening system to enhance punching resistance and combined flexural–punching performance.

Tracing Adaptive Transfer Across Genres and Media: GenAI‐Supported ESL Learners' Digital Multimodal Composing and Traditional Writing Practices

TESOL Quarterly, EarlyView.
Abstract Drawing on the adaptive transfer and the genre knowledge model as a conceptual framework, this research explores how English as a second language (ESL) learners transferred knowledge across genres (narration and argumentation) and media (print‐based writing and video) with the assistance of generative artificial intelligence (GenAI) platforms ...
