Microstructure and mechanical response of transient liquid phase joint in Haynes 282 superalloy

► Transient liquid phase bonding of a newly developed nickel-based superalloy was performed. ► Insufficient diffusion time resulted in the formation of eutectic microconstituent. ► Increased bonding temperature reduced solidification rate, in contrast to general expectation. ► Numerical simulation showed that the behaviour can be explained by deviation from parabolic rule. ► The phenomenon was less pronounced in the Haynes 282 possibly due to its higher Mo content.
