Effect of Heat Treatment on the Compressive Behavior of Zinc Alloy ZA27 Syntactic Foam.

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 from 1.78 to 2.

Mechanical and Microstructural Characterization of an AZ91⁻Activated Carbon Syntactic Foam.

In this study, activated carbon (AC) particles were combined with AZ91 alloy to manufacture a magnesium syntactic foam. This novel lightweight foam has a very low density, in the range of 1.12⁻1.

Molecular dynamics simulation of surface segregation in a (110) B2-NiAl thin film.

Surface segregation in (110) B2-NiAl film approximately 3 nm thick is investigated by using molecular dynamics simulation with a reliable embedded-atom potential. The simulation is performed for the stoichiometric composition at a temperature of 1500 K, just below the melting temperature of the film model. It is found that the (110) surface is structurally stable but develops adatoms, vacancies and antisites.

Interdiffusion and surface-sandwich ordering in initial Ni-core-Pd-shell nanoparticle.

Using molecular dynamics simulation ( approximately 1 mus) in combination with the embedded atom method we have investigated interdiffusion and structural transformations at 1000 K in an initial core-shell nanoparticle (diameter approximately 4.5 nm). This starting particle has the f.
