Abstract: A method for making a single crystal structure. The method including selecting a plurality of single crystal components having a lattice unit cell repeated substantially throughout, the unit cell having a periodic arrangement of atoms defining a set of lattice planes. Determining the orientations of the lattice planes relative to each component. Machining each component along at least one of the set of lattice planes to define a pair of interface surfaces thereon. Applying bonding material to each interface surface. Assembling the components at their respective interface surfaces such that each pair of matching interface surfaces have an orientation substantially aligned along a common one of the set of lattice planes. Heating the components per a predetermined temperature profile until the bonding material melts and fuses the components together.
