| Abstract Scope |
AA6061 is a precipitation-hardened alloy that has found broad applications in research reactors due to its excellent mechanical properties, formability, and good corrosion resistance. It is most widely used in fuel manufacturing, cooling pipes, and framing of nuclear structures. Nuclear fuel pallets are formed using a technique where they are sandwiched between several layers of AA6061 and further enclosed in AA6061-T6. Surface of AA6061 is prone degradation via cacking, abrasion and corrosion. Here, we have modified the surface of AA6061-T6 using Al+Al2O3 via cold spray (CS) followed by friction stir processing (FSP). The effects of FSP on microstructure and mechanical properties as function of temperature will be presented, and avenues for adoption by the nuclear industry will be discussed. |
