Syntactic iron foams have been produced by metal injection moulding techniques from iron powders and commercially available glass microspheres at varied content levels. Quasi-static and high strain-rate dynamic properties are determined and interpreted, showing that the respective materials reveal high strength as well as several points of attack that will allow tailoring their characteristics to meet specific application requirements. The image shows the structure of a material containing 10 wt% of microspheres, etched to visualize grain boundaries.
