| Abstract Scope |
The talk will cover recent works that are exploring the location- and orientation-dependence of mechanical properties in various builds and structures of various materials. Work at CWRU, and in collaboration with others, is examining the microstructure (e.g. morphology and defect density) and mechanical behavior (e.g. tension, fracture toughness, fatigue crack growth, high cycle fatigue) of both specimens and parts made with different materials. In addition to printing and testing bulk samples, miniature samples have been excised from both bulk samples as well as prototype parts for both as-deposited and post-processed builds. Existing and evolving ASTM/ISO standards for additively manufactured materials were used to illustrate the range of microstructural features and mechanical properties that are being reported for a few commonly studied alloy systems and AM techniques. The opportunities and challenges facing the more widespread use of additive manufactured components in structural applications will be discussed. |
