Abstract:

During this project as part of DARPA MCMA we aimed to develop and demonstrate a 3D microstructural architecture structure made from bulk metallic glass, 3DMGS, exhibiting a combination of ceramic-like high strength 1000 MPa, metal-like high plasticity 20, and polymer like density 2 gcm3. We developed novel processing methods such as BMG sheet fabrication and BMG joining. Topological optimization has been used to identify optimized structures for the combination of properties.
