Systematic measurements of the spectra of fluorine K? x-rays produced by the bombardment of alkali and alkaline earth fluorides with 2-MeV/amu ions ranging from He to Ar have given new information on the mechanisms for rapid electron transfer within the K-hole lifetime (~10-13sec.). Spectra obtained with He ions provide clear evidence of the occurrence

Abstract The influence of the densification temperature on the density, microstructure, mechanical properties, resistivity and coercivity of WC- 40 wt%Co composite produced by impact sintering has been investigated. The studied material possessed a 54% volume content of cobalt and tungsten carbide particles of initial size 1–3 μm.

Mechanism Wear of Elastomers with Oblique Impact of Solid Particles in the Aqueous Medium
Journal of Friction and Wear, 2019An experimental study made it possible to identify the stages and mechanism of deterioration of a rubber surface in an aqueous medium for conditions of impact with a single solid particle and impact with a hydroabrasive jet. The deterioration has a fatigue character and is divided into two stages: formation of the primary site of deterioration and ...

The reinforcement of elastomers by inorganic fillers, a concept of very high technological importance, is commonly understood to result from the presence of a mechanical network of partially aggregated filler particles. The non-linear mechanical properties, in particular the decrease of the modulus at high strain (Payne effect), are further interpreted

The relationship between mechanical stress states and interfacial electrochemical thermodynamics of Li metal/Li6.5La3Zr1.5Ta0.5O12 and Na metal/Na-β”-Al2O3 systems are examined in two experimental configurations with an applied uniaxial load; the solid electrolytes were pellets and the metal electrodes high-aspect-ratio electrodes.

Wear Mechanism of Elastomers under the Direct Impact of Solid Particles in an Aqueous Medium
Journal of Friction and Wear, 2018A single impact of a solid particle on the surface of rubber in an aqueous medium is simulated using a special installation. An experimental study made it possible to distinguish the stages and the destruction mechanism of the rubber surface. It is established that rubber wear in an aqueous medium and air have fundamental differences.

AbstractThe coexistence of unstable, metastable, and separated Frenkel pair defects in metals under nonequilibrium conditions generated via impact displacement of lattice atoms by incident particles is studied theoretically. The extent of a spontaneous annihilation (SA) zone of defects along their attraction directions is determined in the framework of

For electromagnetic applications the microstructure and the final mechanical state are key parameters. These can be obtained by a judicious choice of the material, a particular design like laminated steels but also through the determination and the mastering of the fabrication process.

AbstractA general theory is developed of non‐impact mechanisms of the unstable (U), metastable (M), and separated (S) Frenkel pair defect creation in non‐metals that is realized at the decay of excitons, electron‐hole (e‐h) pairs, and holes. A two stage self‐trapping model of excitons (holes) is proposed.
