Plastic deformation down to 4.2 K of CoO single crystals and T.E.M. observation of dislocations
(EDP Sciences, 1988)
Plastic deformation of CoO has been performed at 4.2 K by compression of single crystals along <100>. The influence of thermodynamic conditions of specimen preparation has been shown. The dislocation structure observed by ...

Sintering and Characterization Studies of NiO
(EDP Sciences, 1986)
Des polycristaux de NiO de haute pureté ont été élaborés par frittage avec et sans charge. Ils ont été caractérisés par microscopie optique et électronique. Leur comportement en fluage a été étudié au dessus de 1200°C.

Deformation of MgO by Vickers microindentation tests
(EDP Sciences, 1982)
Vickers microhardness tests have been performed at room temperature on (100), (110), and (111) MgO faces for various orientations of the pyramid diagonal. The indentations may be deformed probably because of cracking. ...

Pure diffusional creep of NiO polycrystals
(European Physical Society (EPS), 1983)
Compressive creep testing of polycrystalline NiO has been performed in air and argon, at temperatures between 1 100 and 1 500 °C (0.61 to 0.79 TM) under loads corresponding to initial applied stresses from 6 to 90 MPa. ...

Estructura de dislocaciones en ZRO2 totalmente estabilizado deformado a alta temperatura
(1989)
Se ha estudiado por microscopía electrónica de transmisión la microestructura de deformación a altas temperaturas (1.300-1.550°C) de monocristales de Zr02-Y203 totalmente estabilizados. La variación observada en la ...

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 ...
