Multi‐Scale Mechanical Behavior of Additive‐Manufactured 316L Stainless Steel Processed by Severe Plastic Deformation

open access: yessteel research international, EarlyView.
The multi‐scale mechanical behavior of additive‐manufactured 316L stainless steel processed by directed energy deposition and high‐pressure torsion is explored. The influence of torsional strain on strength and microstructural evolution is revealed, indicating progressive grain refinement in the ultrafine regime, reaching strength levels nearing 1800 ...

Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review

open access: yesSafety Science and Technology, EarlyView.
This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.

In Situ Construction of Phosphorus‐Containing Crosslinked Urethane Network Combined With Ammonium Polyphosphate via Reactive Blending for Enhancing Flame Retardancy and Anti‐Dripping Performance of Polylactic Acid Composites

open access: yesSafety Science and Technology, EarlyView.
By in situ reaction blending, DOPO‐HQ and THEIC were added to PLA with MDI to construct a phosphorus containing polyurethane network, which significantly improved the flame retardant and anti‐dripping properties of polylactic acid composites. ABSTRACT Polylactic acid (PLA) is highly flammable and prone to severe melt dripping during combustion, which ...

Assessing the fire resistance of damaged reinforced concrete frames: A comparative study between 2D and 3D frames

open access: yesStructural Concrete, EarlyView.
Abstract Post‐earthquake fires pose a significant threat to urban environments, with potentially catastrophic consequences for buildings and infrastructure. To enhance understanding and mitigate these risks, this study conducts a comparative analysis of post‐earthquake fire (PEF) in two‐dimensional (2D) and three‐dimensional (3D) reinforced concrete ...

Pre‐failure behavior of continuous post‐tensioned and post‐grouted beam in case of tendon failure

open access: yesStructural Concrete, EarlyView.
Abstract Grouted tendons are a common solution for long‐span bridge structures. The grout provides bond and corrosion protection for prestressing steel. However, if the grouting is defective, corrosion of the prestressing steel may initiate and eventually lead to tendon failure.
