Plastic deformation of dense nanocrystalline yttrium oxide at elevated temperatures [PDF]
, 2012 Nanocrystalline yttrium oxide, Y2O3 with 110 nm average grain size was plastically deformed between 800 ◦C and 1100 ◦C by compression at different strain rates and by creep at different stresses. The onset temperature for plasticity was at 1000 ◦C. Yield

Advanced Engineering Materials, EarlyView.This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the

Twinning partial multiplication at grain boundary in nanocrystalline fcc metals
, 2009 Most deformation twins in nanocrystalline face-centered cubic fcc metals have been observed to form from grain boundaries. The growth of such twins requires the emission of Shockley partials from the grain boundary on successive slip planes.

Advanced Engineering Materials, EarlyView.The corrosion performance of AlSi7Mg and AlSi10Mg alloys produced through selective laser melting (SLM) was examined under compressive stress in a chloride environment. Electrochemical analyses, including open‐circuit potential (OCP), potentiodynamic polarization (CPP), and electrochemical impedance spectroscopy (EIS), were complemented by scanning ...
