The structure of ice-templated materials is typically defined by two features. At a small scale, a lamellar microstructure, replicating the morphology of the ice crystals, is observed. On a short-range, adjacent lamellaes are parallel to each other. On a longer range, the lamellaes are organized in so-called orientation domains, where all the lamellaes are parallel to each other within a domain. Unless specific processing tricks are used (freezing under flow , applying magnetic fields during freezing , etc.), orientation domains have been observed to be randomly oriented, because of the random selection of the ice crystals in the first instants of freezing. The characteristics of the orientation domains directly impact the mechanical response of the ice-templated materials .
