Influence of severe plastic deformation on the precipitation hardening of a FeSiTi steel [PDF]
, 2012 The combined strengthening effects of grain refinement and high precipitated volume fraction (~6at.%) on the mechanical properties of FeSiTi alloy subjected to SPD processing prior to aging treatment were investigated by atom probe tomography and ...

Microembossing of ultrafine grained Al: microstructural analysis and finite element modelling
, 2010 Ultra fine grained (UFG) Al-1050 processed by equal channel angular pressing (ECAP) and UFG Al-Mg-Cu-Mn processed by high pressure torsion (HPT) were embossed at both room temperature and 300 °C, with the aim of producing micro-channels. The behaviour of

Strain mapping and nanocrystallite size determination by neutron diffraction in an aluminum alloy (AA5083) severely plastically deformed through equal channel angular pressing [PDF]
, 2013 Six specimens of an aluminum alloy (AA-5083) extruded by Equal Channel Angular Pressing following two different routes plus a blank sample were examined with a neutron radiation of 1.5448 Å. Macrostrain maps from the (311) reflection were obtained.

Tailored Sheared Blanks Produced by Incremental ECAP [PDF]
Key Engineering Materials, 2015 Incremental equal channel angular pressing (I-ECAP) is a process used for production of continuous ultrafine grained bars, plates and sheets. Normally the thickness of the processed billet is kept unchanged in consecutive passes to enable repetitive insertion into the same die. This is achieved by controlling the bottom dead centre of the reciprocating

On the Effect of Natural Aging Prior to Low Temperature ECAP of a High-Strength Aluminum Alloy
Metals, 2018 Severe plastic deformation (SPD) can be used to generate ultra-fine grained microstructures and thus to increase the strength of many materials. Unfortunately, high strength aluminum alloys are generally hard to deform, which puts severe limits on the ...

Towards an integrated molecular understanding of plant hormones
Journal of Integrative Plant Biology, EarlyView.This review offers a comprehensive overview of the nine plant hormones, delving into their biosynthesis, transport, signaling and crosstalk mechanisms. Because the complexity of plant hormonal control goes beyond these core elements, additional specific features are discussed. Lastly, this review highlights how fundamental insights drive hormonal‐based
