Abstract According to the IIW recommendation, fatigue strength of welded steel joints is defined as independent base material in case as-welded condition. However, post-treatment techniques can improve performance structures, especially for increased strengths. Therefore, this paper investigates effect TIG dressing, common post-weld treatment method, on high-strength S700 cruciform joints. The ...

Twin-wire and arc additive manufacturing (T-WAAM) has potential advantages in improving deposition efficiency functionally graded materials (FGMs), thus attracting much attention. However, there are few studies on the droplet transfer mode of T-WAAM. This paper analyzes swing “TIG + AC” twin-wire cross-arc by in-situ observation with high-speed photography, revealing what factors influence T-WA...

As CeO2 is a useful catalyst for soot elimination, it important to develop with higher contact areas, and reactivities efficient oxidation catalytic are basically controlled by structures surface properties of catalysts. Herein, Ce-Metal organic framework (MOFs) consisting Ce benzene-1,3,5-tricarboxylic acid (H3BTC) employed as the precursor CeBTC exhibits unique bar-like high-aspect-ratio morp...

The TIG welding process has shallow penetration. addition of activated flux can increase the depth penetration weld, which is called A-TIG welding, so this study to analyze effect type and current on penetration, hardness, microstructure, corrosion rate. This used SUS 304 A36 materials with a thickness 6 mm are welded using variations Fe2O3, Cr2O3 in strength 100 amperes 120 amperes. To find ou...

For the creation of surface reinforcement particles in metal matrix, friction stir processing is frequently utilized. Formation aluminum/SiC composite on Tungsten Inert Gas (TIG) butt weld Al5083 by a novel technique direct (DFSP) using hollow tool successfully demonstrated this present work. Deposition SiC zone DFSP was confirmed X-Ray diffraction (XRD) method. Micro analysis joint achieved me...

Sweet basil (Ocimum basilicum), one of the most popular cultivated herbs worldwide, displays a number of varieties differing in several characteristics, such as the color of the leaves. The development of a reference transcriptome for sweet basil, and the analysis of differentially expressed genes in acyanic and cyanic cultivars exposed to natural sunlight irradiance, has interest from horticul...
