Effect of cobalt oxide on the sintering and grain growth of Al2O3-YAG composite nanopowder [PDF]
Science of Sintering, 2010 In the present study, the effect of cobalt oxide on the densification of Al2O3-YAG composite nanopowder was investigated. An amorphous nanopowder was synthesized and crystallized to Al2O3-YAG after heat-treatment via a solid-state reaction.

Microstructural modelling of creep crack growth from a blunted crack [PDF]
, 1998 The effect of crack tip blunting on the initial stages of creep crack growth is investigated by means of a planar microstructural model in which grains are represented discretely. The actual linking-up process of discrete microcracks with the macroscopic

Li-diffusion accelerates grain growth in intercalation electrodes: a phase-field study
, 2018 Grain boundary migration is driven by the boundary's curvature and external loads such as temperature and stress. In intercalation electrodes an additional driving force results from Li-diffusion. That is, Li-intercalation induces volume expansion of the

A kinetic model for grain growth
Kinetic & Related Models, 2008 We provide a well-posedness analysis of a kinetic model for grain growth introduced by Fradkov which is based on the von Neumann-Mullins law. The model consists of an infinite number of transport equations with a tri-diagonal coupling modelling topological changes in the grain configuration.

Rotation induced grain growth and stagnation in phase field crystal models
, 2013 We consider the grain growth and stagnation in polycrystalline microstructures. From the phase field crystal modelling of the coarsening dynamics, we identify a transition from a grain-growth stagnation upon deep quenching below the melting temperature ...

Growing dust grains in protoplanetary discs - II. The Radial drift barrier problem [PDF]
, 2013 We aim to study the migration of growing dust grains in protoplanetary discs, where growth and migration are tightly coupled. This includes the crucial issue of the radial-drift barrier for growing dust grains.

Synthesis and textural properties of unsupported and supported rutile (TiO2) membranes [PDF]
, 1993 Two approaches were postulated for improving the stability of porous texture of titania membranes: (1) retarding the phase transformation and grain growth; (2) avoiding the phase transformation.

AN ATMOSPHERIC STRUCTURE EQUATION FOR GRAIN GROWTH [PDF]
, 2014 We present a method to include the evolution of the grain size and grain opacity κgr in the equations describing the structure of protoplanetary atmospheres.
