| Abstract Scope |
Stainless-steel cladding plates have become increasingly popular for in-vessel components in both nuclear fission pressure vessel components as well as for nuclear fusion structural components in the blanket module. It utilizes the advantages of limiting expensive alloying elements and high activation at end-of-life while providing a corrosion resistant layer. In joining two dissimilar metals, the interface must be sufficiently bonded to avoid failure via interfacial delamination. The interfacial bond strength is the limiting factor in strength of these components under the stresses induced by load bearing and thermal gradients. Mechanical testing is performed to characterize the explosion welding of AISI 347 stainless cladding to a grade 70 carbon steel base. Compression shear testing is used to define the parameters for a tensile lap-shear testing for miniaturized neutron-irradiated tensile specimens. The composite strength is tested by impact and flexural testing. Fracture surface analysis is conducted to identify the modes of failure. |
