Abstract:
1. A method of manufacturing a turbine component, the method comprising the steps of: forming a plurality of arc segments, each arc segment comprising a single crystal material having a predetermined primary orientation and a predetermined secondary orientation, each predetermined primary orientation of each arc segment being substantially equal, and each predetermined secondary orientation of each arc segment being substantially equal; bonding the plurality of arc segments together into a ring such that each arc segment is adjacent another arc segment, the adjacent arc segments have a bond line therebetween, and the adjacent arc segments have a predetermined crystallographic mismatch therebetween; bonding the ring to a hub to form a disk; and machining the disk to remove at least a portion of the bond line between adjacent arc segments to thereby form a slot in the disk to form the turbine component.
