Abstract: Austenitic–ferritic stainless steels submitted to friction stir welding show good mechanical properties, although there are concerns regarding their application in marine environments, related to their corrosion performance. Friction stir welds of UNS S32101, S32205, S32750,… read more here.

DOI: 10.1177/09544054221111899
Abstract: Friction stir welds were manufactured from aluminum alloy 2024-T3 and 7075-T6 workpieces under temperature control. Three control conditions, high-temperature, low-temperature and uncontrolled, were selected for each alloy based on the precipitation/dissolution temperatures of their strengthening… read more here.
