Bulk nanostructured metals and alloys are finding increasing structural applications due to their superior mechanical properties. The methods that rely on the severe plastic deformation technique for effecting microstructural refinement through imposing large strains utilized mostly produce materials. machining process has been demonstrated as a simple by single pass of cutting tool where in ra...

Predicting the behavior of complex systems is one main goals science. An important example plastic deformation micron-scale crystals, a process mediated by collective dynamics dislocations, manifested as broadly distributed strain bursts and significant sample-to-sample variations in response to applied loading. Here, combining large-scale discrete dislocation simulations machine learning, we s...

Electron backscatter diffraction (EBSD) has been used to examine the plastic deformation of an ex-service 316 austenitic stainless steel at 297K and 823K at strain rates 3.5x10 -3 s -1 – 4x10 -7 s -1 . The distribution of local misorientations was found to depend on the imposed plastic strain following a lognormal distribution at true strains < 0.1 and a gamma distribution at strains > 0.1. At ...
