TL;DR: Tungsten has been chosen as the main candidate for plasma facing components (PFCs) due to its superior properties under extreme operating conditions in future nuclear fusion reactors such as ITER, and careful determination of the threshold parameters for surface recrystallization, grain growth rate, and thermal shock fatigue resistance under ELM-like transient heat events is focused on.

TL;DR: In this paper, the deformation underlying sheet formation is shown to be simple shear that is confined to a narrow zone, which limits the need for pre-heating of the workpiece to realize continuous sheet forms.

TL;DR: This work uses high-speed imaging and micro-marker analysis of flow in cutting to reveal the common fundamental mechanism underlying shear banding in metals and demonstrates a material-agnostic method—passive geometric flow control—that effects complete band suppression in systems which otherwise fail via shear bands.

TL;DR: In this paper, the deformation field in large-strain extrusion machining, a constrained chip formation process, is characterized using high-speed imaging and particle image velocimetry.

TL;DR: In this article, a stochastic crystal plasticity model combining a Monte Carlo method with a polycrystal continuum dislocation dynamics model in a self-consistent viscoplasticity framework is proposed.
