| Abstract Scope |
Although significant commercial and academic resources have been invested in beam-based metal AM, challenges associated with repeated local melting and processing complexity along with high cost equipment and operation are making solid-state AM methods an attractive alternative. In this talk, we discuss the capabilities and challenges of major solid-state AM techniques in two broad categories, deformation-based and sinter-based, based on the metallurgical bonding mechanisms. Limited data available in literature shows that while deformation-based techniques are primarily limited to relatively ductile alloys, a larger variety of materials are suitable for manufacturing through sinter-based AM. Deformation-based methods generally refine the microstructure by recrystallization, while in most cases sinter-based AM methods lead to grain growth due to high temperature processing and a more isotropic microstructure. Among the solid-state AM methods summarized here, binder jetting and additive friction stir AM methods stand out with isotropic microstructures and mechanical properties close to the wrought properties. |
