“…In our case, the foams were made from industrial aluminum (Alfa Aesar, Mexico), with 99.9% purity and density of 2.7 g/cm 3 . This selection was made because of its diamagnetic behavior, low cost, abundance on earth's surface, easy recyclability, and high stiffness in combination with a comparatively low density (Gutie´rrez-Va´zquez and On˜oro, 2008).…”

This article presents the experimental study of a preliminary investigation of a seismic damper device aimed at improving the behavior of structures when subjected to earthquakes. The damper is the result of a binomial material formed by an aluminum foam with pores of 1 mm diameter wetted by a magnetorheological fluid. The objective of this work is to explore the synergy between the two components on a magnetorheological test and to evaluate the effect of the Al foam pores in the structure buildup of the fluid. The analysis is completed with a compressive test carried out on the magnetorheological fluid-filled foam in the presence of a magnetic field. This kind of test demonstrates that the deformation of the foam for very small loads is limited by the hardening of the fluid because of its magnetorheological response. The results of this research suggest that there is a mutual benefit between the components of the device, presumably leading to an enhanced dissipation of vibration energy.

In this work, processes such as additive digital manufacturing (ADM) and precision casting are presented as alternative methods to manufacture aluminum foams with ordered open-pore morphology. Digital modeling of cellular structures with defined regular patterns was manufactured with ABS and wax and then melted in aluminum A356 alloy by a replication casting process. To guarantee the complete filling of the mold, a simulation by the Flow-3D program was made. This computational tool allowed to determine the temperature values of both melting and the mold temperature. The simulations revealed potential defects in the metal foams to be obtained, which were evidenced by the cast pieces processed after as a validation test. The results show that the casting process carried out supported by a computational fluid dynamics (CFD) simulation allows understanding the effects of the simulated parameter process, optimizing the parameters involved in the infiltration process, and establishing the conditions for obtaining a sound piece of open-cell aluminum foam with truncated octahedron pores shape. The established manufacturing process conditions can be used to produce lattice structures with multifunctional uses such as impact and blast-proof devices, vibration attenuators, or where enhancement of heat transfer could be needed.

ResumenEn este trabajo se analiza la influencia de los principales parámetros que intervienen en el proceso de soldadura TIG. Algunos de estos parámetros pertenecen al proceso de soldadura, velocidad de soldadura, intensidad y tensión, mientras otros son propios de las características del material y el utillaje, material precursor y forma de implementar la instalación de ensayo. El resultado de este trabajo muestra una fuerte dependencia de estos parámetros con el proceso de soldadura TIG para las espumas metálicas de aluminio. Palabras claveSoldadura TIG; Espumas de aluminio; Parámetros de soldeo. TIG welding of aluminium foams. Analysis of foaming operating parameters AbstractIn this work the influence of main parameters that take part during TIG welding process are analyzed. Some of these parameters belong to the welding process, as for example the welding speed, intensity and voltage while others are from the material and tooling features, as for example foaming material and tooling design. The result of this work shows a strong dependence on these parameters of the TIG welding process for metallic foams.
