Abstract Scope |
Fusion based additive manufacturing enables site specific microstructure control via control of the local solidification physics. The mesoscale structure, both morphological features and crystallographic texture, can be controlled to some degree. In this work we share recent results using electron beam melting to fabricate 'mesoscale composites' in both a Ni-based superalloy and pure molybdenum. Experiments and microstructure-scale simulations indicate that both macro-scale and localized material behavior may be tailored in these engineered structures. This strategy is potentially suitable for synthesizing optimized materials for use in high temperature applications. |
