This project seeks to integrate irradiation materials science with the practical development of first wall and blanket materials for fusion. Specific focus will be the continued development of sintered copper and ferritic martensitic alloys for application as graded structures in high-heat-flux components.  Developmental materials are to be graded to tungsten, as guided by modeling and informed by our measured non-irradiated and irradiated properties. As a new area we begin limited fabrication and characterization of ultra-high temperature ceramics (UHTC) as potential W HHF replacement. These preliminary studies and preliminary data, when coupled to our ongoing modeling, may suggest a pathway for future work. More significantly, as a means to effectively support our graded structure development we will expand our thermomechanical testing task to include a coupon-scale laser-based high heat flux (HHF) testing capability. This is in addition to our standard micromechanical, tensile and tensile-creep databasing being carried out on non-irradiated and irradiated materials. The coupon-scale HHF capability will be coupled with our in-house x-ray capability and made portable to the NSLS-II (or other synchrotron facility), allowing certain in-operando characterization of graded structures under steady state and pulsed heating.
