NSUF 17-CINR-13004: Capacitive Discharge Resistance Welding of 14YWT for Cladding Applications
The objectives of the proposed work are to join cladding tubes of nano-structured ferritic alloy (NFA) alloy and other oxide dispersion strengthened (ODS) alloys using capacitor-discharge resistance welding (CDRW), a solid-state welding (SSW) process offering extremely rapid thermal cycles with very low overall heat input. CDRW has been applied successfully to other engineering alloys and is especially well-suited for nuclear reactor cladding applications. We hypothesize that the very rapid thermal cycles and lower heat input inherent to CDRW will produce solid-state welds on ferritic ODS alloys with greater retention of strength, radiation damage resistance, and creep resistance properties, relative to those achieved previously with other SSW processes. Moreover, we theorize that CDRW will prove applicable for joining small diameter tubes of NFA/ODS alloys, while also retaining nano-cyrystalline (NC) size distributions that lead to superior ductility and fracture toughness properties.
