The influence of secondary phase particles on grain growth (Zener pinning) is simulated in two dimensions using a level set method. Several simulations with circular particles are performed to study the influence of particle surface fraction and distributi ...
Impurities are known to have a significant impact on materials properties. In particular, the presence of impurities can change mechanical properties and stabilize the microstructure by reducing grain growth and recrystallization processes. In the past ato ...
The paper describes a level set framework for the finite-element modelling of recrystallization in polycrystalline materials, including the nucleation, primary recrystallization and grain growth stages. A set of convection- reinitialization-diffusion equat ...
A detailed investigation was carried out to study the effect of volume fraction on microstructure evolution in segregation-free isotropic volume-conserved two-phase alloys. Large scale two-dimensional (2D) and three-dimensional (3D) simulations were perfor ...
This poster presents the measurement of the forces involved in the hydrophobic self assembly process. More precisely the objects of interest are hydrophilic semi spheres with a gold layer on the flat side. The gold layer has been coated with dodeca thiols ...
Transparent alumina is often processed with sintering additives such as, Y, La, and Mg, in order to limit its grain growth at high sintering temperatures. Usually, these additives segregate to the grain boundaries due to their larger cationic size than Al ...
Pure and barium titanate (BT) powders doped with different lanthanum concentration were prepared by the polymeric precursor method (Pechini process) which was carried out as a three-stage process from organometallic complexes. Sintering of pressed powders ...
Grain boundaries (GBs) play an important role for the mechanical properties of metals. In addition to dislocation motion inside the grains, some metal alloys deform along the GBs at high temperatures. GBs can also be the cause of a brittle behaviour of som ...
A comprehensive particle size distribution model has been developed for the simulation of gamma' precipitation in multicomponent Ni alloys. Nucleation, growth and coarsening of the precipitates are described by a particle size distribution. The growth rate ...
An equilibrated polycrystalline material is considered, containing a small fraction of void space (melt or vapor), for which the crystals are above their roughening transition against this medium. The grain boundaries are approximated to have equal free en ...
