Multifaceted Behavior and Versatility Features of Ferritic Stainless Steels, Part II: Investigating Electromagnetic, Mechanical, and Corrosion Behavior

steel research international, EarlyView.
This review's second part details the mechanical, corrosion, and electromagnetic behaviors of FSSs. It integrates the foundational microstructure (texture/defects/precipitates) and processing effects from Part I to establish and analyze complex property–property interrelationships critical for high‐performance applications.

Microscopic Stress Analysis of Silicon Carbide Devices Under Overcurrent Conditions in DC Solid‐State Circuit Breakers

IET Smart Energy Systems, EarlyView.
A coupled Saber–TCAD–thermo‐mechanical simulation framework is proposed to evaluate microscopic stresses in SiC MOSFETs under overcurrent operation. Ultrahigh gate‐voltage driving reduces thermal and mechanical stress but increases gate oxide electric‐field stress, revealing a reliability tradeoff for DC solid‐state circuit breakers.

Adhesion of Newly Developed Composite Resin Splinting Materials to Enamel: Effect of Enamel Surface Treatment

Dental Traumatology, EarlyView.
ABSTRACT Background/Aim To evaluate the shear bond strength (SBS) of newly developed composite resin materials intended for dental splinting to enamel and to determine whether phosphoric acid etching alone provides reliable adhesion. Material and Methods Four experimental materials (G‐Fix, Light Fix, Ortho Connect, and Ortho Connect Flow) were compared

Optimizing diphenyl(2,4,6‐trimethylbenzoyl)phosphine oxide concentration and post‐curing time to balance mechanical properties and color stability in a three‐dimensional‐printed restorative resin

European Journal of Oral Sciences, EarlyView.
Abstract Three‐dimensional (3D) printing is widely used in dental restorations; however, optimization of photoinitiator concentration and post‐curing protocols remains critical to achieve a balance between mechanical and esthetic performance. This study evaluated the combined effect of diphenyl(2,4,6‐trimethylbenzoyl)phosphine oxide (TPO) concentration

Silicon Carbide/Silicon and Silicon Carbide/Silicon Carbide Composites Produced by Chemical Vapor Infiltration

Journal of the American Ceramic Society, 1990
Composites of SiC/Si and SiC/SiC were prepared from single yarns of SiC. The use of carbon coatings on SiC yarn prevented the degradation normally observed when chemically vapor deposited Si is applied to SiC yarn. The strength, however, was not retained when the composite was heated at elevated temperatures in air. In contrast, the strength of a SiC/C/
