In Situ X-Ray Radiography and Tomography Observations of the Solidification of Alumina Particles Suspensions. Part I: Initial Instants
Sylvain Deville, Eric Maire, Audrey Lasalle +4
This paper investigates by in situ high-resolution X-ray radiography and tomography the behaviour of colloidal suspensions of alumina particles during directional solidification by…
In Situ X-Ray Radiography and Tomography Observations of the Solidification of Alumina Particles Suspensions. Part II: Steady State
Sylvain Deville, Eric Maire, Audrey Lasalle +4
This paper investigates the behaviour of colloidal suspensions of alumina particles during directional solidification, by in situ high-resolution observations using X-ray radiograp…
Microstructural investigation of the aging behavior of composites
Sylvain Deville, Jérôme Chevalier, Christelle Dauvergne +4
The low temperature autoclave aging behavior of zirconia toughened alumina composites processed by a classical powder mixing processing route was analyzed using atomic force micros…
Atomic force microscopy of transformation toughening in ceria-stabilized zirconia
Sylvain Deville, Hassan El Attaoui, Jérôme Chevalier
We demonstrate in this paper that atomic force microscopy can be successfully used to gain further insights into the understanding of transformation toughening in ceria stabilized…
Atomic force microscopy study of the tetragonal to monoclinic transformation behaviour of silica doped yttria-stabilized zirconia
Sylvain Deville, Jérôme Chevalier, Laurent Gremillard
The tetragonal to monoclinic phase transformation of zirconia has been the subject of extensive studies over the last 20 years [1-4]. The main features of the transformation have b…
Ice-templated porous alumina structures
Sylvain Deville, Eduardo Saiz, Antoni P. Tomsia
The formation of regular patterns is a common feature of many solidification processes involving cast materials. We describe here how regular patterns can be obtained in porous alu…
