| Abstract Scope |
Ultrasonic additive manufacturing (UAM) is a promising solid state joining technique for producing planar geometries. While established for other materials, use of UAM to fabricate composite structure using zirconium alloys for nuclear reactor applications is in early development. Development of more complex geometries and structures must be preceded by studies that establish UAM can produce materials of acceptable properties. The corrosion behavior of Zry-4 during exposure to water coolants and the oxidation of Zry-4 in high temperature steam and oxygen are critical performance metrics. Residual voids formed between layers of Zry-4 tape used in the UAM process and other heterogeneities are not present in conventional Zry-4 processing, and their impact must be understood. The oxidation behavior of Zry-4 is studied here alongside conventionally manufactured Zry-4 using exposures in TGA furnaces at temperatures 600-1200°C for up to 100 h. Hydrothermal corrosion is also compared using continuously refreshing autoclave exposures for ≥1,000h. |
