Growth and interaction of dendritic equiaxed grains: In situ characterization by synchrotron X-ray radiography
A.-A. Bogno,A.-A. Bogno,Henri Nguyen-Thi,Henri Nguyen-Thi,Guillaume Reinhart,Guillaume Reinhart,Bernard Billia,Bernard Billia,José Baruchel +8 more
TL;DR: In this paper, the growth and interaction of primary dendrite arms, which drive and limit grain development, were analyzed through measurements of the lengths and tip velocities of the primary dender arms driving grain growth.

TL;DR: In this paper, the structure of the β-phase has been redetermined at ambient temperature as well as in situ at 400°C, and the reciprocal space, Bragg and diffuse scattering, has been explored as a function of temperature and the β − to β −phase transition was studied in detail.
Journal ArticleDOI
Analysis by synchrotron X-ray radiography of convection effects on the dynamic evolution of the solid–liquid interface and on solute distribution during the initial transient of solidification
A.-A. Bogno,A.-A. Bogno,Henri Nguyen-Thi,Henri Nguyen-Thi,A. Buffet,Guillaume Reinhart,Guillaume Reinhart,Bernard Billia,Bernard Billia,Nathalie Mangelinck-Noël,Nathalie Mangelinck-Noël,N. Bergeon,N. Bergeon,José Baruchel,Thomas Schenk +14 more
TL;DR: In this paper, a detailed analysis of the evolution over time of the solid-liquid interface macroscopic shape in interaction with convection in the melt was carried out by means of synchrotron X-ray radiography.
Journal ArticleDOI
On the interest of synchrotron X-ray imaging for the study of solidification in metallic alloys
Henri Nguyen-Thi,Henri Nguyen-Thi,Luc Salvo,Ragnvald H. Mathiesen,Lars Arnberg,Bernard Billia,Bernard Billia,Michel Suéry,Guillaume Reinhart,Guillaume Reinhart +9 more
TL;DR: In this paper, the authors present illustrative results of the current capabilities of synchrotron X-ray imaging in this field of research, each of them using different Xray techniques (radiography, topography and tomography).
Journal ArticleDOI
In situ observation of solidification patterns in diffusive conditions
TL;DR: A review of recent in situ experimentation studies of solidification front patterns and microstructures in alloys can be found in this paper, where the dynamics of cellular, dendritic, and eutectic growth patterns in diffusive-growth conditions, that is, in the absence of convection in the liquid.
