| Abstract Scope |
Metallic foams are prized for their light-weight properties and unique mechanical performance, but are limited in application due to the costly, resource-intensive nature of production. Current production methods also limit the materials that can be processed into foams, with most foams made of aluminum given its low melting point. Our study demonstrates that metallic foams of varying densities can be produced by compressive loading machining chips of a chosen alloy together, creating strong bonds between contact points while preserving large pores/voids to maintain the foam-like nature of the material. This variable porosity can be used to tune the modulus of materials, a parameter that is otherwise difficult to change, as well as other added benefits like vibration dampening and shock absorption. By consolidating chips together in their solid state, the energetic cost of foam production is drastically decreased while simultaneously widening the material options from which foam can be made. |
