| Abstract Scope |
In a wide field of solid state material production, the unintended or inhomogeneous incorporation of foreign phases is a limiting issue. The basic understanding of mechanics and phenomena, which lead to engulfment and incorporation of foreign phases, mostly in form of small particles or bubbles, is essential to overcome the problem and to increase production yield.
The work presented here is investigating the fundamental, physical basics of the interaction of those foreign phases with the solid-liquid interface during material solidification out of melt and the surrounding fluid. This is a complex system with a high number of influencing forces. For the experiments, microgravity is substantial to exclude the influence of gravity and all gravitational driven forces. With these simplifications, the experimental results can be easily compared to theoretical calculations based on existing and/or adapted models.
The direct observation is realized by using an optically transparent melt system with opaque particles. |
