Yes! The turbine blades in jet engines are single crystals of typically Ni or Co based alloys that are grown in a mold. It’s more of a directional solidification process though, I don’t think you could grow a NaCl crystal from solution like this in a mold https://www.appropedia.org/Single_Crystal_Turbine_Blades#Manufacturing_Process_and_Crystal_Growth https://www.appropedia.org/Single_Crystal_Turbine_Blades#Man...
