Plastic deformation of CoO single crystals
(EDP Sciences, 1980)
Constant strain rate compressions along < 001 > have been performed on CoO single crystals (ε ∼ 6 x 10-5 s-1). Yield stresses and work hardening rates have been measured between 77 K and 1 400 K; CoO is very strong when ...

Fluage de monocristaux de NiO
(European Physical Society (EPS), 1978)
NiO single crystals have been subjected to constant-load compressive creep along (100). Stresses between 50 MPa and 120 MPa and temperatures between 950 °C and 1 200 °C were studied. The activation energy observed suggests ...

Model of high-temperature plastic deformation of nanocrystalline materials: Application to yttria tetragonal zirconia
(2003)
The possibility of the influence of segregation-induced local electric fields in the bulk diffusion of the species controlling the plastic deformation of nanocrystalline materials has been pointed out. Until now, there is ...

Exotic grain growth law in twinned boron carbide under electric fields
(Elsevier, 2018)
Grain growth is a ubiquitous phenomenon in all materials, and it affects both structural and functional prop- erties. Despite its intrinsic importance, a full comprehension of grain growth from a fundamental point ...

Superplasticidad en materiales cerámicos. Aplicaciones
(1997)
Las características generales macroscópicas y microscópicas de la superplasticidad son analizadas en detalle. Mediante el análisis de resultados experimentales en policristales de circonia dopada con ytria, se propone una ...
