Co-based superalloys are a particular class of metallic materials widely used in aerospace industry for the production of jet engine components. These alloys provide great corrosion resistance at high temperatures, this combined with the retention of mechanical properties at elevated temperatures make these alloys the reference materials for applications in aggressive environments subject to high temperatures. The growth of additive manufacturing technologies has allowed these alloys to be used for the production of components of complex geometry, expanding their uses. Co-based superalloys are characterized by a γ phase, which is Face centered cubic (FCC) and an ε phase, which is Hexagonal closed packed (HCP).
