TL;DR: In this article, the residual stress profiles in aluminum and steel welds, and in shot peened aluminium, obtained via synchrotron and neutron diffraction at the ESRF-ILL in Grenoble, were presented.

TL;DR: In this article, a systematic approach to optimising FSW process parameters (tool rotational speed and feed rate) through consideration of frictional power input is presented, and it is shown that rotational speeds are the key parameter governing tool torque, temperature, frictional powers and hence tensile strength and fatigue performance.

TL;DR: In this paper, the effect of varying welding parameters on residual stress profiles in friction stir welds of aluminium alloy AA5083-H321, which were created on a fully instrumented friction welding machine, was determined non-destructively using synchrotron X-ray diffraction.

TL;DR: In this paper, specific influences of the friction stir welding process on crack paths and dynamic performance for 5083-H321 and 5383-h321 aluminium alloys are presented, and an explanation for the weld microstructures and thermomechanical history is proposed.

TL;DR: In this article, the potential of information contained in the microhardness and residual transverse strain profiles just below the weld toe and at mid-depth in the plate, to predict the fatigue performance ranking for a series of 12 MIG welds made in RQT701 steel under different conditions.
