Friction stir-based channeling is a solid-state processing encompassing the friction stir (FSC) and its variants. In one manufacturing action, FSC delivers subsurface internal closed channel in monolithic plate with no length limitation. The unique characteristics of theses internally channels produced can fit demand from several industrial fields, namely lightweight structurally stiffened pane...

Friction stir welding is a solid-state joining process widely used in several industrial applications. One of its variants, orbital friction welding, key importance fundamental industries such as oil and gas aerospace. For there need to develop not only new parameters but also tools ancillary mechanisms that can ensure sound, high-performing joints are obtained. This review assesses the current...

The results of numerical calculation the continuum mechanics equation for continuous medium plastic flow and analytical models studying thermophysics at friction stir welding are given.
