Back stress strengthening and strain hardening in gradient structure [PDF]
, 2016 We report significant back stress strengthening and strain hardening in gradient structured (GS) interstitial-free (IF) steel. Back stress is long-range stress caused by the pileup of geometrically necessary dislocations (GNDs).

Ellipticity loss analysis for tangent moduli deduced from a large strain elastic–plastic self-consistent model [PDF]
, 2009 In order to investigate the impact of microstructures and deformation mechanisms on the ductility of materials, the criterion first proposed by Rice is applied to elastic–plastic tangent moduli derived from a large strain micromechanical model combined ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Hardening of an Al-Cu-Mg alloy containing type I and II S phase precipitates
, 2010 The effect of different thermo-mechanical treatments on the hardness of the 2024 (Al-Cu-Mg) alloy was studied. Artificial ageing was conducted through heating at a constant rate to specific temperatures followed by rapid cooling.
