TL;DR: In this article, the applicability of hot working of metals and alloys is reviewed in the context of their applicability to friction stir welding (FSW) and friction stir processing (FSP) and two of these models are used to interpret microstructure and microtexture data for two aluminum alloys subjected to FSP.

TL;DR: In this paper, a plate of as-cast NiAl bronze (NAB) material was sectioned from a large casting and a six-pass fusion weld overlay was placed in a machined groove; a portion of the weld reinforcement was removed by milling and a single friction stir processing (FSP) pass was conducted in a direction transverse to the axis of and over the weld overlay.

TL;DR: In this article, the relative contributions of grain-boundary sliding (GBS) and solute drag creep (SDC) to the deformation of fine-grained AA5083 materials were examined.

TL;DR: In this paper, the deformation field associated with the creation of a machined surface was measured and it was shown that the strains in the surface and chip are large and essentially equal.

TL;DR: The microstructure and microhardness of copper subjected to large strains either using one or a combination of severe plastic deformation (SPD) processing techniques was evaluated in this paper, where the individual SPD techniques used include equal-channel angular pressing (ECAP), high-pressure torsion (HPT), and chip formation during machining (M).
