Manufacturing and compressive properties of sandwich foam tubes containing metal syntactic foam Open
This paper is concerned with sandwich foam tubes (SFTs), a recent type of sandwich structure containing metal syntactic foam (MSF). To create these structures, MSF is cast between thin-walled aluminium tubes in a single-step counter-gravit…

Self-diffusion in a triple-defect A-B binary system: Monte Carlo simulation Open
In this comprehensive and detailed study, vacancy-mediated self-diffusion of A- and B-elements in 'triple-defect' B2-ordered ASB(1-S) binaries is simulated by means of a kinetic Monte Carlo (KMC) algorithm involving atomic jumps to nearest…

Effect of Heat Treatment on the Compressive Behavior of Zinc Alloy ZA27 Syntactic Foam Open
Zinc alloy (ZA27) syntactic foams (SF) were manufactured using expanded perlite (EP) particles and counter-gravity infiltration casting. Due to a variation of the metallic matrix content, the density of the produced foam samples varied fro…
