Ni-based superalloys are high-temperature materials employed e.g. in turbines. They gain their high strength by precipitation hardening. The unique thermal history encountered by the material during LAM, which includes rapid cooling from the melt, cyclical re-heating and/or an elevated processing temperature due to preheating, influences the number density and size distribution of the precipitates. For the same reason, unwanted defects, such as hot cracks, can occur in the material.
