“…On the other hand, due to their high strength up to ~400 °C, good ductility, high thermal and electrical conductivity along with their commercial availability, precipitation hardened CuCrZr alloys have been chosen as heat-sink materials for International thermonuclear experimental reactor (ITER) high heat flux (HHF) components such as the divertor, limiter and first wall of the reactor vacuum vessel [2,[4][5][6]. Moreover, they exhibit high fracture toughness and high resistance to radiation damage, allowing them to be good candidates for heat sinks in HHF applications in the baseline design of the prototype power plant DEMO [7,8].…”
