TL;DR: A heterogeneous lamella structure in Ti produced by asymmetric rolling and partial recrystallization that can produce an unprecedented property combination: as strong as ultrafine-grained metal and at the same time as ductile as conventional coarse- grained metal.

TL;DR: In this article, a simple equation and a procedure are developed to calculate back stress basing on its formation physics from the tensile unloading-reloading hysteresis loop.

TL;DR: A three-level heterogeneous grain structure with grain sizes spanning the nanometer to micrometer range, imparting a high yield strength well in excess of 1 GPa leads to a sustainable strain hardening rate, a record-wide hysteresis loop in load−unload−reload stress−strain curve and hence high back stresses.

TL;DR: In this paper, the authors combine the benefits from both gradient structure and transformation-induced plasticity (TRIP) for 304 stainless steel, and the resulting TRIP-gradient steel takes advantage of both mechanisms, allowing strain hardening to last to a larger plastic strain.

TL;DR: In this paper, a single-phase CrCoNi medium-entropy alloys (MEA) with various heterogeneous microstructures, using cold rolling followed by annealing at various temperatures, was characterized using hat-shaped specimens in Hopkinson-bar experiments.
