Abstract Scope |
Microstructural features such as twins and grain boundaries directly impact mechanical behavior in metals and when engineered can push properties to new extremes. We have recently developed an additive manufacturing technique which converts hydrogels printed via vat polymerization into metal and metal alloy structures through a calcination and reduction process. With this unique manufacturing methodology, we can push materials into non-equilibrium microstructures, such as heavily twinned grains, opening a new space for material design and fundamental investigation of nano-plasticity. Through EBSD, TEM, and a suite of nanomechanical experiments, we show the impact of processing on microstructural features and mechanical properties. This work provides direct insight to micro- and nano-scale mechanical properties of materials made through this unique process and highlights the opportunities for novel microstructural engineering of additively manufactured metals and metal alloys. |
