Residual stresses, microstructure and tensile properties in Ti-6Al-4V friction stir welds
This paper reports the results of a systematic investigation of residual stresses as a function of welding speed in a set of Ti-6Al-4V friction stir welds. The investigation focuses on residual stress but links these data with microstructural information derived from micrographs and hardness measurements as well as mechanical testing results. Residual stresses were determined using energy dispersi
