CETSOL-1 is a European Space Agency (ESA) experiment that belongs to the Transparent Alloys series, which aims to study different physical phenomena that take place during directional solidifications under microgravity conditions. In particular, the goal of this new experiment is to identify the growth of the columnar structures (known as dentrites), the equiaxed grains, the mixed formation of both structures as well as the physical mechanisms that intervene in their evolution. The microgravity conditions of the ISS allow the science team to study three dimensional phenomena without the influence of natural convection, so the experiment is performed in pure ... Read More
