North Carolina State University proposes to characterize the high temperature materials properties of a diffusion welded laminated structure and to develop the ASME Code methodologies for preventing failure of a printed channel and hybrid compact heat exchangers under sustained and cyclic pressure and thermal loading of high temperature nuclear service. This will be accomplished by conducting tensile, creep, fatigue, and creep-fatigue tests using uniaxial specimens machined from diffusion welded Type 316H stainless steel an Alloy 617 solid blocks, conducting room temperature burst tests and high temperature cyclic pressure tests, and performing elastic-perfectly plastic analysis.
