Deliverables: Fundamental properties of nickel billet. Report of ultrasonic properties (sound velocity, attenuation, and backscattered noise) and types of defects of concern in IN718, Waspaloy, and IN901. Report of characterization of defects and ultrasonic properties (sound velocity and acoustic impedance) as a function of composition for defects in IN718. Representative sample blocks and synthetic inclusion samples. Metrics: Assessment of ultrasonic properties for typical nickel alloys and characterization of melt-related defects that support the needs of inspection development, POD estimation, and life management.
