Alloy modification for additive manufactured Ni alloy components Part I: Effect on microstructure and hardness
- Alloy 36 is an iron-based alloy with 36% nickel. It is used in applications in which dimensional stability is critical, such as molding tools for composite materials in aerospace and automotive applications. Moreover, increasingly complex structures and the optimisation of resource efficiency also require additive manufacturing steps for the production or repair of components. Additively manufactured components have a heterogeneous microstructure and anisotropic mechanical properties. In addition, the manufactured components require subsequent machining surface finishing due to the high requirements. Nickel iron alloys are difficult to machine. Additionally, inhomogeneous microstructure may lead to unstable cutting forces and conditions. Alloy modifications are made to the alloy 36. For this purpose, titanium, zirconium and niobium are added up to 1 % by mass each. Plasma-Transferred-Arc is used for the welding tests. The hardness profile is determined on the transverse section.

The initial structure as well as the modifications have an austenitic structure. The microstructure of the modifications of Alloy 36 with 1% Ti and 1% Zr is not refined, instead the grain size increases.…
