Abstract

1430587 Soldering FULMER RESEARCH INSTITUTE Ltd 3 Jan 1974 [12 Oct 1972] 47046/72 Heading B3R In bonding two parts selected from Ti alloy, Nb, Nb alloy, Ni alloy and stainless steel, an interlayer selected from Mg, Sn, Al/Cu composite and Al is interposed between the parts, the assembly is heated while under pressure to cause the formation of a liquid phase due to melting of the interlayer material or of a eutectic mixture formed between the interlayer material and either of the parts to be bonded, the amount of interlayer material being such that no insoluble intermetallic compound is formed, and the pressure and temperature is maintained until the liquid phase has diffused into the parts. Each part may be of Ti alloy, Nb, Nb alloy or Ni alloy when the interlayer is of Mg, Sn or Al and Cu composite and when both parts are of Nb, Nb alloy or Ni alloy the interlayer may be of Al. A Ti alloy, Nb or Nb alloy part may be joined to a stainless steel part using Mg or an Al and Cu composite. The interlayer may be in the form of a foil or a layer produced by electro or vapour plating or by evaporation and joining, e.g. to form a T joint may take place in an atmosphere of argon or helium or in vacuo. In examples two pieces of Ti-6Al-4V alloy are assembled with (a) Mg and (b) Sn foil and the assembly is pressed and heated for 24 hours in vacuo at 870‹ C. In another example the foil employed is a composite roll bonded Al and Cu foil layer, a greater pressure being employed but for only 1 hour. One of the Ti alloy pieces is replaced by a Nb piece when heating is effected at 900‹ C. for 1 hour and in another example two pieces of Ni- Cr-Co-Ti-Al alloy are assembled with Mg foil and heated under pressure at 900‹ C. for 24 hours.
