The creep rupture test at 600℃ of brazed joint of AISI 316 type austenitic stainless steel has been examined. The brazed joint was made with 21Pd-48Ni-31 Mn filler metal under the heating conditions of 1,180℃×2min and cooling rate of 130℃/min in 5×(10)^<-4> Torr atomosphere. From the test results, it is clear that the brazed joint used is difficult to apply in practice, because of the very scattered values of its rupture strength. This unstable test results are cused by microcracks in the dendrites occured at solidification of filler metal. Accordingly, an improvement of the brazed joint may expected by controlling the growth of dendrites. In this study, this control is carried out with the addition of a little titanium to the filler alloy used, for the prevention of the growth of dendrites in brazed metal.
