Hydrogen environment embrittlement of astroloy and Udimet 700 (nickel-base) and V-57 (iron-base) superalloys [PDF]

The sensitivity to hydrogen environment embrittlement of three superalloys was determined. Astroloy forgings were resistant to embrittlement during smooth tensile, notched tensile, and creep testing in 3.5-MN/sq m hydrogen over the range 23 to 760 C. The

Structure and Thermodynamical Properties of Zirconium hydrides from first-principle

, 2011
Zirconium alloys are used as nuclear fuel cladding material due to their mechanical and corrosion resistant properties together with their favorable cross-section for neutron scattering.

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

Structural 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.

Processing Stabilization of Polyolefin Recyclates Using Alditols in Combination With α‐Tocopherol: A Sustainable Alternative to Phosphites

Journal of Vinyl and Additive Technology, EarlyView.
A novel bio‐based stabilizer system significantly improves the quality of polyolefin recyclates during multiple recycling cycles. ABSTRACT This study introduces a novel bio‐based stabilizer system for polyolefin recyclates that combines alditols with small amounts of α‐tocopherol as a sustainable alternative to conventional phosphite additives. The aim

Effects of autoclave sterilization on the dimensional stability of implant surgical guides: A 3D in vitro analysis

Journal of Prosthodontics, EarlyView.
Abstract Purpose Surgical guides are medical devices used in static implant surgery to replicate the prosthetic and surgical implant position planned with computer‐assisted software before surgery. Their use reduces invasiveness and improves safety and outcomes of implant surgery, provided that their accuracy is ensured from design to manufacturing and

Performance of PBF‐Printed Micro‐Channel Bipolar Plates as a Function of Flow‐Field Parameters and Plane Area

Fuel Cells, Volume 26, Issue 3, June 2026.
ABSTRACT SUS 316L bipolar plates (BPPs) with rectangular micro‐channels for polymer electrolyte membrane fuel cell (PEMFC) were fabricated using powder bed fusion (PBF) technology, and the effects of flow‐field structure parameters (channel width, rib width, and channel depth) on fuel cell performance were analyzed.

Effect of heat treatment on microstructure and hydrogen embrittlement of additively manufactured and cast 18Ni300 maraging steel

Journal of Materials Research and Technology
The microstructure is significantly different between cast and additively manufactured 18Ni300 maraging steel due to the different manufacturing principles. The resulting differences in hydrogen embrittlement susceptibility need to be clarified. Electron

Mitigation of UV‐Induced Degradation in Lightweight SHJ Solar Modules via a UV‐Downshifting Encapsulation Strategy

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 6, Page 771-785, June 2026.
Lightweight SHJ solar modules with UV‐downshifting encapsulants effectively mitigated UV‐induced degradation (UVID). However, a reduction in the downshifting (DS) effect was observed, supposedly caused by photooxidation. A novel dual‐layer encapsulation was proposed to ensure the UV utilization and stability of lightweight SHJ solar modules, preserving
