The space holder process (SHP) is a useful and common technique to obtain metal foams. However, an important question remains unsolved: Would the quality of salt affect properties aluminum foam obtained? In this paper, removable preforms two types (refined unrefined) were infiltrated with A356 alloy foams different pore sizes. interaction preform-metal was studied from analyzing morphological s...

The A356 aluminum alloy is a very commonly used in the automotive industry, for parts such as pistons, cylinder heads, and connecting rods, which mechanical properties can be effectively increased by anodizing. In this work, oxide layers were formed oxalic acid solution with defined parameters on then studied using novel combination of scanning electron microscope (SEM) in-situ nanoindentation....
