Abstract

In this study, solid-state welding of boron-doped Ni3Al with Ti-6Al-4V was carried out to determine the nature of the interface species and bonding. The interface was examined with SEM, EDS, and micro-hardness tests. Interface stress distribution induced due to different thermal expansion properties was studied with ANSYS modeling. Due to eutectic transformation phenomenon occurring at the interface of boron-doped Ni3Al with Ti-6Al-4V couple, a brittle dendritic structure formed and the mismatched thermal expansion properties of materials led to crack formation at the welding zone. Also, a comparison of the interface zones for boron-doped Ni3Al with Ti-6Al-4V and boron-doped Ni3Al with AISI 304 stainless steel was provided to demonstrate different interface characteristics.
