The goal of this project is to design lamellar (multilayered) shape memory alloy structures (LSMAS) for additive manufacturing (AM) and demonstrate the ability to engineer the AM build plan tune the performance. Employ laser directed energy deposition additive manufacturing (LDED) using elemental Ni and Ti powder. Correlate bulk/meso-scale shape memory properties to the hierarchical microstructure using high throughput local measurements.
