Characterization of Superplastically Formed Friction Stir Weld in Titanium 6AL-4V: Preliminary Results
Source abstract
Abstract
A collaborative University and Industry research project was undertaken to evaluate the performance of as friction stir welded (FSW) and friction stir welded and superplastically formed (FSW-SPF) titanium 6Al-4V alloy sheets. The purpose of this initial phase of research is to test and evaluate the mechanical properties of FSW and post SPF-FSW 2-3 mm thick sheets of titanium. As-FSW and FSW with SPF Ti alloy (standard and fine grain size) butt joints were characterized in terms of microstructures, micro-hardness, metallurgy and tensile properties. The preliminary results of the FSW and post FSW-SPF joint were found to be close to that of as-received titanium with respect to strength, but elongations were decreased.
