| Abstract Scope |
Fuel system consisting of Zr-laminated U-10Mo monolithic fuel cladded in AA6061 are being explored for research and test reactors. The structural integrity of the hot isostatically pressed (HIP) AA6061 cladding is one of critical performance parameters, particularly due to the microstructural changes including excessive development of dispersoids/precipitates and recrystallization that occur during HIP and cooling. This study examines the development of dispersoids/precipitates and grain structure at the AA6061/AA6061 HIP interface as functions of HIP temperatures and cooling rates. Findings of the study will be presented with quantitative microstructural analyses, and discussed with respect to strength, ductility and toughness at the AA6061/AA6061 HIP interface. |
