Optimization of FSW parameters for maximum UTS of AA6082/SiC/10 composites

Advanced Composites Letters, 2019
Friction stir welding (FSW) offers significant advantage when compared with fusion joining process such as no shield gas or flux are used, no harmful gases are produced, thereby making the FSW environmentally friendly.

Microstructural Characteristics and Mechanical Properties of Water Cooling Bobbin-Tool Friction Stir Welded 6063-T6 Aluminum Alloy

MATEC Web of Conferences, 2018
In this study, a novel welding method called water cooling bobbin-tool friction stir welding (WBT-FSW) was developed. 4 mm-thick 6063-T6 aluminum alloy sheets were successfully jointed by WBT-FSW.

FSW varjenje bakra

, 2021
V diplomskem delu smo prikazali varjenje dveh bakrenih zlitin Cu-HCP (CW0021A/C10300) in Cu-ETP (CW004A/C11000). Podrobneje smo opisali kemijsko sestavo bakra in opisali njegove fizikalne lastnosti. Na kratko smo podali opis legiranja bakra z drugimi elementi in nastanek zlitin po legiranju.

Engagement in sexual healthcare and STI/HIV burden of first- and second-generation migrant and Western-born female sex workers in the Netherlands: A retrospective cohort study

Journal of Migration and Health
Introduction: Scarcely available European studies suggest that migrant female sex workers (FSW) have a higher likelihood of sexually transmitted infections (STI) but a lower likelihood of HIV compared to non-migrant FSW. This study assessed demographics,
