Influence of the manufacturing heat cycles on the CuCrZr properties

Characterization of CuCrZr and CuCrZr/SS joint strength for different blanket components manufacturing conditions

“…In the main, there is no abnormal outcome compare to [2][3][4][5]. As expected, the best result concerning tensile strength (YS and UTS) is obtained with route C3 (classical and optimal heat treatment conditions).…”

“…Initially, the manufacturing condition retained was a HIP treatment combined with a fast cooling plus a subsequent ageing treatment, and several studies have been conducted assuming this manufacturing route [2][3][4][5][6]. But for safety of the HIP vessel reasons, it was decided to perform a separate heat treatment after a conventional HIP treatment, normal cooling %8°C/mn.…”

“…Different temperatures, cooling rates and duration of temperature step are possible and their effects had to be investigated. Ageing temperature and treatment duration after a HIP quench have been explored thoroughly in several studies [2][3][4][5] as well as the precipitation in the material [6,7]. The manufacturing conditions are presented in Table 1.…”

Pre-series and testing route for the serial fabrication of W7-X target elements

“…With the present route, this process is not feasible anymore because the tiles are joined to a cooling structure with the cooling channels already machined. The electron beam welding process used for the manufacture of the cooling structure and for the bonding of the tiles to the cooling structure are always followed by an age-hardening heat treatment process to recover CuCrZr properties [10].…”

Fabrication and characterization of tungsten and graphite based PFC for divertor target elements of ITER like tokamak application

“…divertor target and dome, is an important area of interest in tokamak plasma fusion research [1][2][3][4][5]. Joining of plasma facing materials i.e.…”
