Abstract This work presents the design and fabrication of a simple device for manufacturing metal foams composites using infiltration. The particularities operation this are also included here, detailing examples materials manufactured it. was thought to produce matrices from low medium melting points (e.g., Mg Cu alloys), limited ~1200 °C. It can be used samples large enough their study characterization, being cheaper than other devices reported in literature. Foams different sizes...
This work analyzes the effect of Cu additions on microstructure quaternary alloys Al-6Si-7Mg-xCu (x= 3, 5 and 7 wt.%) produced by conventional metallurgy. Microstructural modifications were studied using Optical Microscopy (OM), X-Ray Diffraction (XRD) Scanning Electron (SEM), focusing second phases identification quantification. Conventional image analyses developed measuring total percentage phases, individually for each phase determining its equivalent diameter, shape factor, roundness...
The effect of space holder particles (SHP) fractal distribution on the porosity aluminum foams manufactured by infiltration is studied in present work. Physical models were used to estimate foam porosity, simulating SHP for bimodal mixtures with different particle sizes and relative quantities. Results these compared mathematical results obtained experimental using a 332 Al-alloy base material NaCl grains as SHP. Experimental structural characterization was carried out image analysis obtain...

This work analyzes the combined use of Discrete and Finite Element Methods (DEM FEM, respectively), in order to obtain models fractal metallic foams close real experimental manufactured infiltrating space holder particles, then evaluate their mechanical behaviors using FEM. Firstly, DEM was used generate coordinates for locating pores different sizes, which were modeled a second step To validate estimations obtained aluminum evaluated through compressive tests. Fractal combinations holders...
importance of using models according to the real topology defined by manufacturing process.
