The processing and properties of syntactic Al foams containing low cost expanded glass particles (2016)
Journal Article
Wright, A., & Kennedy, A. R. (in press). The processing and properties of syntactic Al foams containing low cost expanded glass particles. Advanced Engineering Materials, https://doi.org/10.1002/adem.201600467

Expanded glass particles (EGP) are used to manufacture Al syntactic foams using a simple vacuum casting method. Clamping of the casting in the stainless steel mold is observed when preheating the mold to >400?C, causing damage to the EGP, resulting i...
