Acoustical properties of Ni3Al single crystals alloyed with cobalt and niobium

High-temperature nickel-base alloys (superalloys) are widely adopted in industry as materials for structural elements of devices operating upon high temperatures (aerospace turbine blades, etc.). Successful application of these alloys is based on their high mechanical properties. Today, the range of service conditions expands toward progressively higher temperatures. Thereupon, the investigation of mechanical and thermal properties of nickel high-temperature alloys appears to be a topical question.
