Cohesive and adhesive properties of polycaprolactone/silica hybrid coatings on poly(methyl methacrylate) substrates

Organic–inorganic hybrid materials were prepared using the sol–gel process in order to improve the scratch resistance of poly(methyl methacrylate) (PMMA) substrates. Sol–gel solutions based on tetraethoxysilane and α,ω-triethoxysilane terminated polycaprol ...

Correlation between oxygen transport properties and microstructure in La0.5Sr0.5FeO3-δ

Jan Van Herle, Philippe Buffat, Stefan Diethelm, Joseph Sfeir

The effect of the bulk microstructure (grain size distribution, grain boundary composition on the oxygen transport properties of La0.5Sr0.5FeO3membranes was investigated. For this purpose, samples with different microstruct ...

HOW DOES COALESCENCE OF DENDRITE ARMS OR GRAINS INFLUENCE HOT TEARING ?

Michel Rappaz, Jean-Marie Drezet, Alain Jacot, Vincent Mathier, Piero Daniele Grasso

Hot tearing, a severe defect occurring during solidification, is the conjunction of tensile stresses which are transmitted to the mushy zone by the coherent solid underneath and of an insufficient liquid feeding to compensate for the volumetric change. In ...

Influence of microstructure on oxygen transport in perovskite type membranes

Jan Van Herle, Philippe Buffat, Stefan Diethelm, Joseph Sfeir

The effect of the bulk microstructure (grain size distribution, grain boundary length) on the oxygen transport properties of permeation membranes is investigated in this work. For this purpose, La0.5Sr0.5FeO3-? samples with different microstructures have b ...

Modélisation des transformations de phase à l'état solide dans les aciers et application au traitement thermique par induction

Alain Jacot

In the first part of this work a comprehensive model of the continuous hardening of 3D-axisymmetric steel components by induction heating has been developed. In the model, the Maxwell and heat flow equations are solved using a mixed numerical formulation : ...

Kinetics of densification by solution-reprecipitation

Andreas Mortensen

The densification rate and microstructural evolution of powder compacts densifying by solution-reprecipitation in the presence of a liquid phase are predicted with the assumption that solid particles are equisized spheres randomly packed and pulled togethe ...

The Laguerre model for grain growth in three dimensions

Thomas Liebling

We propose a novel and poweful methodology for three- dimensional (3D) grain growth modelling in both the anisotropic and the locally inhomogeneous cases, thus significantly generalizing previous related two-dimensional work. The fundamental modelling stru ...
