Strain weakening and superplasticity in a Bi-Sn eutectic alloy processed by high-pressure torsion
, 2014 High-pressure torsion (HPT) was conducted on disks of a Bi-Sn eutectic alloy under a pressure of 6.0 GPa. The microstructural evolution was studied by scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD). Measurements of Vickers

, 2014 A common picture of the metaphysics of time has it that the past cannot change. For example, if it is now the case that Obama was born in 1961, it will never be the case that he was not born in 1961. A semantic consequence of this view is the following: (TP) Context-insensitive, temporally specific sentences about the past are truth-value-persistent ...

Ergodicity of the tip of an SLE curve [PDF]
, 2013 We first prove that, for $\kappa\in(0,4)$, a whole-plane SLE$(\kappa;\kappa+2)$ trace stopped at a fixed capacity time satisfies reversibility. We then use this reversibility result to prove that, for $\kappa\in(0,4)$, a chordal SLE$_\kappa$ curve ...

MICROSTRUCTURE AND MECHANICAL PROPERTIES OF ULTRA-FINE GRAINED AZ31 ALLOY PROCESSED BY ECAP
Acta Metallurgica Slovaca, 2014 Commercial magnesium alloy AZ31 was processed by equal channel angular pressing preceded by hot extrusion (EX-ECAP). Microstructure evolution with strain due to ECAP was investigated by light and transmission electron microscopy. ECAP processing resulted

SIMULATING OZONE EFFECTS ON FOREST PRODUCTIVITY: INTERACTIONS AMONG LEAF‐, CANOPY‐, AND STAND‐LEVEL PROCESSES [PDF]
, 1997 Ozone pollution in the lower atmosphere is known to have adverse effects on forest vegetation, but the degree to which mature forests are impacted has been very difficult to assess directly.

Editorial for ECAP, July Issue 2010 [PDF]
European Child & Adolescent Psychiatry, 2010 More and more studies deal with the problem of gene 9 environment interaction (G 9 E) to explain the origins and courses of child psychiatric disorders [3]. However, this kind of knowledge is still in its infancy and few of these G 9 E effects have been sufficiently replicated [8]. Nevertheless, the results can and should be introduced already in today’

Effect of Equal Channel Angular Pressing (ECAP) on Erosion-Corrosion of Pure Copper
Applied Sciences, 2017 During the past few decades, ultrafine-grained materials (UFG) have experienced rapid development. Enhanced mechanical and surface properties, such as strength, ductility and erosion-corrosion (E-C) resistance by refining the grain to ultra-fine ...
