Effect of the degree of plastic deformation on the thermal electromotive force of cu-x5crni1810 steel thermocouple [PDF]

open access: yesScience of Sintering, 2018
The thermal electromotive force (TEMF) and the thermal electromotive force coefficient (TEMFC) of the thermocouple consisting of a copper wire and an (X5CrNi1810) steel wire plastically deformed under tension or bending conditions were found to ...

Reversible plasticity in amorphous materials [PDF]

open access: yes, 2007
A fundamental assumption in our understanding of material rheology is that when microscopic deformations are reversible, the material responds elastically to external loads. Plasticity, i.e. dissipative and irreversible macroscopic changes in a material,

Physics of phonon-polaritons in amorphous materials [PDF]

open access: yesThe Journal of Chemical Physics, 2021
The nature of bosonic excitations in disordered materials has remained elusive due to the difficulties in defining key concepts such as quasi-particles in the presence of disorder. We report on an experimental observation of phonon-polaritons in glasses, including a prominent boson peak (BP), i.e., excess of THz modes over the Debye law.

Enhanced stability and local structure in biologically relevant amorphous materials containing pyrophosphate [PDF]

open access: yes, 2011
There is increasing evidence that amorphous inorganic materials play a key role in biomineralisation in many organisms, however the inherent instability of synthetic analogues in the absence of the complex in vivo matrix limits their study and clinical ...

Influence of grinding and pressing of the powder 50.0 wt% Fe, 47.0 wt% BaTiO3 and 3.0 wt% TiO2 on morphology, microstructure and magnetic properties [PDF]

open access: yesScience of Sintering
Mixing the powders Fe (50.0 wt%), BaTiO3 (47.0 wt%) and TiO2 (3.0wt%) provides a mixture consisting of a matrix of smaller particles BaTiO3 in which larger particles Fe and TiO2 were embedded.

Influence of grinding, pressing and sintering of the powder 50.0 wt% Fe, 47.0 wt% BaTiO3 and 3.0 wt% TiO2 on morphology, microstructure, magnetic and electric properties [PDF]

open access: yesScience of Sintering
A mixture of 50.0 wt% Fe, 47.0 wt% BaTiO3, and 3.0 wt% TiO2 powders is milled and then pressed and sintered. Samples sintered from ground powders have a structure consisting of plates.

Relaxation and derelaxation of pure and hydrogenated amorphous silicon during thermal annealing experiments [PDF]

open access: yes, 2010
The structural relaxation of pure amorphous silicon (a-Si) and hydrogenated amorphous silicon (a-Si:H) materials, that occurs during thermal annealing experiments, has been analysed by Raman spectroscopy and differential scanning calorimetry. Unlike a-Si,
