A microanalysis investigation of an embrittled stainless steel sheath

Diffusion bonding of titanium to 304 stainless steel

“…Extensive work has already been reported to produce diffusion bonded joints of commercially pure Ti (CP-Ti) to the austenitic stainless steel (SS) [16][17][18]. The earlier work on diffusion reaction between Ti/stainless steel indicated the formation of Fe, Cr and Ni based intermetallic compounds [15][16][17][18][19]. It is also suggested that the formation of intermetallic compounds is more significant for the diffusion couple annealed above 900°C [16].…”

“…All these deleterious effects ultimately lead to premature failure of components in service condition.
