Strain hardening recovery mediated by coherent precipitates in lightweight steel [PDF]
Scientific Reports, 2021 We investigated the effect of κ-carbide precipitates on the strain hardening behavior of aged Fe–Mn-Al-C alloys by microstructure analysis. The κ-carbides-strengthened Fe–Mn-Al-C alloys exhibited a superior strength-ductility balance enabled by the ...

Extraordinary strain hardening by gradient structure [PDF]
Proceedings of the National Academy of Sciences, 2014 Significance Nature creates the gradient structure (GS) for a purpose: to make biological systems strong and tough to survive severe natural forces. For the grain-size GS, the deformation physics is still unclear. One wonders if the grain-size GS in the nanomicroscale would also benefit materials engineered by mankind.

Strain Hardening in Polymer Glasses: Limitations of Network Models [PDF]
, 2007 Simulations are used to examine the microscopic origins of strain hardening in polymer glasses. While traditional entropic network models can be fit to the total stress, their underlying assumptions are inconsistent with simulation results.
