Invar alloys are known and widely employed for their dimensional stability. These alloys have uniquely low thermal expansion up to the Curie temperature. This magnetic phase transition temperature in the Invar alloy system varies with the Ni content. Consequently, Invar alloys are flexible for use in a broad temperature range depending on the Ni content. In this respect, wire and arc additive manufacturing presents the opportunity for in-situ alloying through multi-wire deposition. Therefore, this study utilises a dual-wire deposition approach to fabricate a graded Invar wall and a block of Invar 42. We present and discuss the prime aspects of the in-situ deposited Invar alloy concerning the deposition, composition and thermal expansion coefficient.
