Be–Cu joints based on amorphous alloy brazing for divertor and first wall application

Development of rapidly quenched brazing foils to join tungsten alloys with ferritic steel

“…Rapidly solidified amorphous and microcrystalline foiltype filler metals represent a promising approach for the joining of dissimilar materials [4,6,7]. They offer a number of advantages -extremely high chemical and phase uniformity, narrower melting and solidification ranges, 'instantaneous' melting across the whole width and thickness of the foil, and outstanding ductility.…”

“…Amorphous foils bend 180°without fracturing and thus accommodate complex joint geometries. The rapidly solidified filler metal STEMET â has been used to join dissimilar PFC materials,including Cu and graphite, Mo and graphite, V and graphite, Be and Cu, V and Be, and SS and Be [6,7].…”

Microstructural evolution in the partial transient liquid phase diffusion bonding of Zircaloy-4 to stainless steel 321 using active titanium filler metal

“…Such formation is very serious when fusion occurs, as in arc-welding. In order to avoid the formation of intermetallic compounds several processes have been developed [8][9][10][11].…”

Development of brazing foils to join monocrystalline tungsten alloys with ODS-EUROFER steel

“…For a number of applications, a suitable brazing has demonstrated significant advantages in comparison with fusion and pressure welding [3,7,8]. Rapidly solidified amorphous and microcrystalline foil-type filler metals represent a promising approach for the joining of dissimilar materials [4,[6][7][8].…”

“…Rapidly solidified amorphous and microcrystalline foil-type filler metals represent a promising approach for the joining of dissimilar materials [4,[6][7][8]. For example, the brazing of powder metallurgy tungsten and monocrystalline tungsten to a Cr13Mo2NbVB ferritic/martensitic steel was carried out using a rapidly solidified 35-40 lm thick foil-type filler metal (Ni bal -15Cr-4Mo-4Fe-(0.5-1.0)V-7.5Si-1.5B) in vacuum at 1150°C, using a 0.5 mm thick spacer made of a 50Fe-50Ni alloy to decrease the residual thermal stresses in the brazed joint [6].…”
