In this study, the effect of temperature on the microstructure and reactive layer at the interface between the Ti interlayer and the base metal related to the diffusion bonding of Zr۷۰۲ to A۵۱۶ low alloy steel was investigated. The joining was done using the spark plasma sintering technique at temperatures of ۹۰۰, ۹۵۰ and ۱۰۰۰°C for ۳۰ minutes. Field Emission Scanning Electron Microscope (FESEM) equipped with EDS analysis was used to investigate the microstructure of the interfaces in various joints. Investigations showed that at all temperatures, with the diffusion of atoms and the formation of a reactive layer between the Ti interlayer and Zr۷۰۲, no intermetallic phases, cracks, porosity and discontinuities were formed at their interfaces. . It was found that increasing the bonding temperature did not cause the formation of new phases and compounds in the interface and only increased the thickness of the reaction layer. The measurement of the thickness of the reactive layer showed that the maximum and minimum amounts of diffusion were ۸۴ microns at ۱۰۰۰ °C and ۶۴ microns at ۹۰۰ °C respectively
