Abstract:

In this study, the effect of diffusion bonding temperature on microstructure properties of Zr/Ti interlayer in the diffusion bonded joints of Zr۷۰۲ to A۵۱۶ low alloy steel was performed. diffusion bonding was performed by SPDB method using spark plasma sintering technique (SPS) at temperatures of ۱۰۰۰, ۹۵۰ ℃ and ۹۰۰ in ۳۰ minutes. To study the microstructure of the interfaces in different joints, a field emission electron microscope (FESEM) equipped with an EDS analyzer was used.The results showed that diffusion was well done in the interface of all interlayers at all three temperatures and no intermetallic phases, cracks and discontinuities were observed in the diffusion zone. three solid solution phases were observed in all of diffusion zones: (α+β)(Zr,Ti), α(Ti,Zr) andβ(Ti,Zr). Also, the thickness of the diffusion zones was measured, with the highest diffusion in sample number one with a thickness of ۸۲.۹۷۹ microns and the lowest diffusion in sample number three with a thickness of ۶۴.۲۳۵ microns.
