Reduction of Oxide Inclusions During the High‐Frequency Welding of Steel via a Nonthermal Ar/H2 Plasma Jet

Advanced 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 ...

A Nonlinear Finite Element Modeling For High Strength Fibrous Reinforced Concrete Beams

Sulaimani Journal for Engineering Sciences, 2017
This paper presents a nonlinear finite element model to investigate the influence of steel fibers on the flexural strength of high strength reinforced concrete beams. Two methods had been used to model the steel fiber using ANSYS 14.

Structural performance of steel-concrete sandwich beams with carbon nanofiber reinforcement [PDF]

, 2019
Cementitious materials such as concrete are typically characterised as quasi-brittle with low tensile strength and low strain capacity, which hence affect the long-term durability of the structure.

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere

Advanced Engineering Materials, EarlyView.
A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.

Experimental investigation on flexural performance of corroded RC beams with high-strength concrete and steel bars

Case Studies in Construction Materials
The flexural performance of corroded reinforced concrete (RC) beams has been well studied experimentally during the past years. In the available experiments, however, the specimens are commonly designed with the strengths of steel bars and concrete below

Dynamic response of GFRP-reinforced UHPC beams under close-in blast loading

Materials & Design, 2022
Combined use of ultrahigh-performance concrete (UHPC) with glass fiber reinforced polymer (GFRP) reinforcement has the potential for further blast resistance enhancement of reinforced concrete (RC), due to the improved toughness of UHPC and the high ...
