Scope Advancements in additive manufacturing technology have created the ability to design and construct parts with geometries and properties that cannot be achieved through traditional machining processes. This ability has promoted new design strategies whose success relies on close integration of engineering with materials science. Of particular interest is tailoring specific material properties in low volume production. In principle, engineers can now ‘print’ 3-dimensional external shapes with complex internal features that can be optimized to meet a wide range of operational constraints and service conditions. As part of this optimization, the material properties can be modified at critical areas in the component. The 3-dimensional nature of the mesoscale can now be shrunk down to the microscale where properties are controlled by the local 3-dimensional microstructures. An additional attractive aspect of the additive process is the ability to custom design specific properties within the component by layering different materials during the build process. The repetitive rapid solidification that occurs during the fabrication process is dominated by transient phenomena, which can create unexpected variations in the composition and performance of the component. Thus, optimizing this process and the desired properties requires integrating a variety of computational and experimental methods across a variety of time and length scales. This includes detailed 3-dimensional characterization as well as numerical modeling of the thermodynamics. The transient nature of the rapid solidification can result in non-equilibrium phases, which result in properties which differ from wrought.

The main objective of this symposium is to provide a forum to discuss ways to integrate approaches to develop customized, low volume production components with customized material properties. This includes increasing our understanding of the relationships between complex microstructures and mechanical behavior with regards to the influences of repetitive rapid solidification on resulting phase transformations and their influence on the strengthening mechanisms.

Abstracts are requested in the following general topic areas relating to additive manufacturing and its influence on phases and properties: transient phenomena, phase transformation, and rapid solidification.
