چکیده

We discuss the coarsening process of melt inclusions inside a solid phase. Elastic effects lead to an oblate shape of the particles, resulting in a system with strong diffusional and elastic interactions between inclusions. The usual mean-field approximation breaks down and several independent length scales have to be taken into account. In a system of parallel oriented particles we find scaling laws for the coarsening of the different length scales involved. In particular, the lateral size of the particles obeys a nontrivial growth law, R approximately t(5/12).

Morphological evolution during phase separation and coarsening with strong inhomogeneous elasticity

We studied the morphological evolution during spinodal phase separation and subsequent coarsening in systems with a strong dependence of elastic constants on the composition. An efficient numerical method is developed for solving the two-dimensional inhomogeneous elastic equilibrium equations by using the conjugate gradient method. A simple model binary system with a symmetric miscibility gap i...

Influence of Stresses on Precipitation

Precipitation, which usually occurs by nucleation, growth and coarsening, may be affected by elastic stresses which influence the thermodynan~ics of the system and thereby the driving force for precipitation. Such stresses may be internal, e.g. coherency stresses, or external, i.e. externally applied stresses. The consequences for nucleation, growth and coarsening are discussed in detail with s...

Quantum dots of CdS synthesized by micro-emulsion under ultrasound: size distribution and growth kinetics

Quantum dots of CdS with hexagonal phase were prepared at relatively low temperature (60 oC) and short time by micro-emulsion (O/W) under ultrasound. This study was focused on the particle size distribution and the growth kinetics. The particle size distribution obtained from the optical absorption edge. It was relatively symmetrical with sonication time. In addition, an agreement was observed ...

Dynamics of Phase Separation in Confined Two-component Fluid Membranes

We investigate the dynamics of phase separation in two-component fluid membranes confined between parallel and rigid bounding plates. Through numerical simulation, we find dramatic slow coarsening of the order parameter field within the simulation time. In particular, a microphase separation is obtained as an equilibrium phase for sufficiently large values of the elastic coupling, being consist...

محاسبه کرنش الاستیک هم سیمایی برای مورفولوژی های مختلف رسوبات ’γ در یک سوپر آلیاژ پایه نیکل

Coherency elastic strain between γ and  is one of the effective factors which affect the morphology, spatial re-arrangement and coarsening kinetics of  precipitates in nickel-base superalloys. In this investigation, using X-ray diffraction (XRD) technique, the - constrained and unconstrained lattice misfits were calculated for different morphologies of the  precipitates in Inconel 738L...
