Friction stir process (FSP) was conducted in both air and water on aluminium alloy AA7075,
with the latter environment providing the smallest grain size and a higher surface copper …

To improve the accuracy of numerical simulation of friction stir welding (FSW) process, the
tool tilt angle must be considered as a significant parameter. In this study, specific …

The majority of this research has concentrated on developing the self-support friction stir
welding (SSFSW) tool which consists of a big concave upper shoulder and a small convex …

The increasing industrial demand for lighter, more complex and multi-material components
supports the development of novel joining processes with increased automation and …

Samples of 6082-T6 aluminum alloy were welded by bobbin tool friction stir welding at
different rotational speeds. The thermal cycles, microstructure, microhardness, and tensile …

Temperature variations during friction stir welding result from the heat generated by the
frictional action of a rotating tool on the workpiece. This temperature distribution affects the …

Friction stir welding (FSW) is a reliable joining technology with a wide industrial uptake.
However, several fundamentals of the process such as the temperature inside the stirred …

The effect of post weld heat-treatments (PWHT) on the mechanical and fatigue crack growth
of friction stir welded 7075-T651 aluminum alloy was investigated. The PWHT of natural …

Friction stir welding is a relatively novel solid state method which produces ultra fine-grained
microstructure and promoted mechanical properties due to the severe plastic deformation …

Process parameters and base material thermal properties strongly affect peak temperature
evolution in friction stir welding (FSW). This work develops a semi-empirical model for peak …
