3D metallic glass cellular structures

3D Metallic glass structures (3DMGs) are fabricated through thermoplastic forming (TPF)-based patterning of MG sheets combined with a parallel joining technique. To demonstrate this capability and benchmark 3DMGs, we have fabricated honeycomb-like MG architectures covering a wide range of relative densities. 3DMGs exhibit high elasticity of up to 40% loading strain, high elastic energy storability, and high energy absorption which is superior compared to those made from other materials such as conventional metals and ceramics, based on our theoretical analysis. The combination of MG properties and introduced versatile fabrication method suggest the possibility of developing a wide range of 3DMGs with excellent performance for specific applications. A scalable fabrication method for 3DBMG structures by thermoplastic forming and parallel joining is introduced. Experimental characterization and theoretical analysis of 3D BMGs' mechanical behaviors reveal excellent elasticity and elastic energy storability paired with very high energy absorption ability. The combination of BMG properties and the developed versatile fabrication method suggest the possibility to develop a wide range of BMG structures with excellent performance for specific applications.
