Grain boundaries are interfaces that separate different crystallographic regions, known as grains, within a polycrystalline material. In nanomaterials, grain boundaries play a crucial role in ...

EQUILIBRIUM segregation of impurities or solute elements has frequently been suggested as a cause of grain boundary embrittlement in metals and metallic compounds, but the evidence has been ...

Welker, of Seimens Schuckertwerke, Erlangen. Etching of the surface has revealed grain boundaries, and annealing twins. Etch pits have also been observed along slip lines.

Recently, we proposed a universal descriptor for grain boundaries that has desirable mathematical properties, and which can be applied to arbitrary grain boundaries. Using this descriptor, we were ...

Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds.

Domain wall movement at and near engineered 10º, 15º, and 24º tilt and 10º and 30º twist grain boundaries was measured by band excitation piezoresponse force microscopy for Pb(Zr,Ti)O3 films with ...

The matlab code called GBvelocityOrderParam.m allows you to calculate and plot the graphs of distance vs time vs temperature of grain boundaries in a bicrystal sample ...

Creep mechanisms are studied in θ′-Al2Cu-strengthened Al-Cu-Mn-Zr alloys at 300 and 350°C for (i) ACMZ, a base alloy without further alloying elements and (ii) RR350, a commercial alloy with additions ...

All these applications are based on the highly nonlinear, fast, and reversible electrical switching characteristics of a single grain boundary with a switching voltage of ≈3.2–3.6 V in the ...
