Single Crystal Blade

A gas turbine blade composed of a single metallic crystal. Conventionally cast turbine airfoils are polycrystalline, consisting of a three-dimensional mosaic of small metallic crystals, or grains, that form during solidification in the casting mold. A single crystal blade structure can withstand creep at higher temperatures than crystalline turbine blades due to the absence of grain boundaries.
