The Isothermal Dendritic Growth Experiment (IDGE) is a materials science solidification experiment that researchers will use to investigate a particular type of solidification called dendritic growth. Dendritic solidification is one of the most common forms of solidifying metals and alloys. When materials crystallize or solidify under certain condition, they freeze unstably, resulting in tiny, tree-like crystalline forms called dendrites. Scientist are particularly interested in dendrite size, shape, and how the branches of the dendrites interact with each other. These characteristics largely determine the properties of the material.
