| Abstract Scope |
The implementation of fusion energy faces fundamental materials issues, especially with respect to the interface between plasma facing materials (PFM) and structural materials. Tungsten is a commonly chosen PFM, whereas steel is desirable for the structural component of fusion reactors. The interface between tungsten and steel can host severe internal stresses, due to their inherent differences in thermal and mechanical properties. Thus, this work investigates the mechanical properties of laminate composites comprised of thin foil layers of tungsten and Grade 92 steel. These laminate composites were fabricated via forging and hot rolling at 1000˚C with 20% total reduction. Two different versions of these composites were investigated, with varying foil thicknesses. One was comprised of alternating layers of 100 μm tungsten and 100 μm steel, and the other with layers of 25 μm tungsten and 100 μm steel. For evaluation, tensile testing and elemental analysis were performed on both laminate composites. |
