This project aims to implement the physical simulation of friction stir welding (FSW) on UNS S32750 duplex stainless steel using a thermomechanical simulator. FSW is a solid state joining process proposed in 1991 by The Welding Institute in United Kingdom, which allies a range of technical and economic advantages over fusion welding.FSW has been mainly studied and used on low melting poin…
This research project aims to study the dissimilar joining of aluminum and steel using the friction stir welding (FSW) process. The study will establish the welding parameters effect on the joint microstructural evolution and the microstructure effect on the mechanical performance of such welded joint. The proposed configuration is a 2 mm thick butt joint involving AISI 1020 mild steel an…
This project aims the development and application of advanced techniques of Quantitative High-Resolution Transmission Electron Microscopy (HRQTEM) by the analysis of gadolinium-doped ceria (CGO) samples, material correlated to many technological issues, especially Solid-state Oxide Fuel Cells (SOFC). The proposed research focuses on evaluating Gadolinium (Gd) and Oxygen Vacancies (O) dist…
