Figure 3

SEM-picture of an open-cell Fe0.6P structure (a) and light-microscopic cross section of the etched material (b). The microstructure displays the typical perlitic-ferritic structure of an hypoeutectoid steel. Dark dots represent micropores. SEM-picture of a cross section of an open-cell Fe0.6P structure (c) and EDX-Mapping of the same strut (d). The mapping shows a unifomly distributed phyosphorus content.
