PURPOSE:To provide a joint of dissimilar materials where the activity of the joined interface is increased and the joinability is excellent by using powder tantalum or green sheet as an insert. CONSTITUTION:Powder tantalum 3 whose grain size is 30-40mum and whose thickness is 1mm is inserted as an insert between metallic zirconium 1 and stainless steel 2, and the compression joining is executed under the conditions where the temperature is approximately 1000 deg.C, and the pressure is >=1000 atm in the hot press method. This method provides an excellent joint of dissimilar materials of metallic zirconium 1 and stainless steel 2. Excellent adhesion is obtained by the unidirectional compression, the control precision of the temperature and the pressure is especially improved, the process is relatively simple, and a joint of dissimilar materials of metallic zirconium and stainless steel is obtained at low cost. |
