“…Various mockups with different dimensions and coating layers were fabricated to find an optimized bonding condition and canning methods for the HIP. Also, cyclic HHF tests were performed for the validation of the joining integrities of the mockups using various test facilities [7][8][9]: Be/Cu mockup tests in the Russian TSEFEY facility [4], and Be/Cu/SS mockup tests in JUDITH-2 [3].…”

“…This machine will be utilized for a cyclic heat flux test of plasma facing components. Several facilities are now operating in EU FZJ (JUDITH-2 200 kW) [3], US SNL (EB1200) [2], and RF Efremov institute (IDTF 800 kW) [4]. We will perform a non-destructive test for a small-scale mockup with this electron beam facility.…”

“…We have fabricated and tested the first wall mockups to qualify the manufacturing process, which makes the bonding between beryllium, as a PFC, and heat sinkers, such as Cu and stainless steel (SS). These types of mockups were tested using the international round robin test [1] in several electron beam facilities of the US [2], EU [3], Russia [4], etc. In 2009, through the contracts between the ITER Organization and all parties, each party has fabricated the first wall qualification mockups for the heat flux test in the US and EU.…”

Au-Ge-Ni solder was chosen for brazing of the Cu-Cr-Zr alloy cylinder and a part with a cylindrical hole (sleeve) below 550 • C. The Au based solder was first sintered on the surface of the cylinder and then brazed to the inner surface of the sleeve. The effects of the heating process, the temperature and the holding time at the temperature on the microstructure of the sintered layer on the surface of the cylinder, the brazed interfacial microstructure, and the brazed shear strength between the cylinder and the sleeve were investigated by scanning electron microscope, energy dispersive X-ray spectroscopy analysis, and tensile shear tests. By approach of side solder melt feeding and brazing under proper parameters, the voids and micro cracks due to a lack of enough solder melt feeding are greatly lessened and the brazed shear strength of 100 MPa is ensured even with large clearances around 0.01 mm.

Vacuum diffusion bonding of stainless steel to copper was carried out at a temperature ranging from 830 to 950°C under an axial pressure of 3 MPa for 60 min with three kinds of interlayer metals: tin-bronze (TB) foil, Au foil, and TB-Au composite interlayer. The results showed that the grain boundary wetting was formed within the steel adjacent to the interface due to the contact melting between TB and Au when TB-Au composite interlayer was used. The grain boundary wetting could occur at a relatively low temperature of 830°C and becomes significant with the increase of temperature. The tensile strength of the joint with TB-Au was higher than that with TB or Au interlayer separately and could be 228 MPa at the joining temperature of 850°C. Furthermore, the axial compression ratio of the specimen joined at 850°C was approximately 1.2%. Therefore, a reliable and precise joining of stainless steel to copper could be realized by diffusion bonding with the TB-Au composite interlayer at a comparatively low temperature.
