Description
An investigation is presented into the influence of friction stir welding (FSW) process parameters (tool rotation speed and feed rate) on the mechanical properties and microstructure of welded joints of AA2095 (Al, 4.6%Cu, 1.14%Li) in as-welded and PWHT conditions. Welding trials using a cylindrical threaded FSW tool were undertaken to construct a matrix of process conditions. PWHT consisted of natural ageing by solution heat treatment. Mechanical properties were characterised by tensile tests and Vickers microhardness measurements. Correlations between tensile properties and microstructural features, such as the swirl zone in the as-welded condition and abnormal grain growth in the PWHT condition, were studied.
