Production of Open Cell Bulk Metallic Glass Foam Structures via Electromechanical Forming
Abstract
The goal of this work was to develop and optimize an electromechanical joining technique to facilitate the creation of a periodic, three dimensional open cell bulk metallic glass (BMG) foam structure. As stated in the proposal, the relevant tasks for this work were: 1) Design and construct an electromechanical joining system to join cross-stacked BMG wires or wire mesh layers via homogenous flow at points of electrical contact. 2) Characterize the microstructure and strength of the joint interface. 3) Examine the mechanical behavior of the mesh and foam structures produced by this technique, in particular the room temperature tensile and compressive strength and plastic deformation, and compare these results with open cell foam models. 4) Extend the technique to the production of other, more complex lattice geometries. While the first two objectives have been met, meshes and three dimensional foams were not produced due to technical difficulties and delays with the development of the joining system. This work will continue as an unfunded project in the PI's research group.
