摘要

Fabrication of multilayered plasma facing components (PFC) in fusion devices is associated with the production of joints between dissimilar materials. This overview discusses existing techniques for joining beryllium to steels, common fabrication issues and possible solutions. The following two primary joining techniques are discussed in detail: hot isostatic pressing (HIP) and brazing. An evaluation of the mechanical properties of the joints is provided, with limited comparison where relevant.
