Effects of heat treatment on compressive properties of AZ91 Mg and SG91A Al foams with open-cell structure

The compressive properties of open-cell aluminum foams are numerically studied using representative volume elements by means of the finite element method. Four face body centered cubic cell arrangements are analyzed, namely uniform-size with spherical pores and dual-size with spherical pores. The results demonstrated that a cell configuration with dual-size pore arrangement presents improved properties for applications subjected to compression loading. This is attributed to the introduction of secondary pores in the cell structure that provide an increase in the specific stiffness and strength of open-cell aluminum foams.

This paper presents a study of heat treatment on the quasi-static and dynamic compressive properties of the open cell aluminum alloy foams in as-fabricated (F), age-hardened (A) and T6-strengthened (T6) conditions. Although the strain rate and heat treatment of foams are different, all exhibit similar deformation behavior in the subsequent deformation. The yield stress of foams at different strain rates are improved by heat treatment, all exhibit some strain rate sensitivity. However, the densification strain of foams is not sensitive to heat treatment.

In this study, porous bioceramics (titanium foam with diamond-like carbon coatings, glass foam and zirconium oxide foam) were produced using expansion in vacuum. The porosity, the pore size and pore morphology can be adjusted in agreement with the application. The different 3D structures were obtained by varying the parameters of the process. The microstructure and morphology of the porous materials were observed by scanning electron microscopy (SEM) and optical microscopy. The foam exhibit an open-cell structure with interconnected macropores, which provide the potential for tissue ingrowths and the transport of the body fluids.
