Processing, Properties and Coating of Micro‐Porous Syntactic Foams

Production and Properties of 316L Stainless Steel Cellular Materials and Syntactic Foams

“…Nevertheless, even higher‐melting alloys like FeNi36 and FeNi50, which necessitate sintering at 1000°C, can be processed showing only slight deformation of the glass microspheres. Their somewhat surprising resilience under such adverse conditions is explained by assuming that early initiation of sintering among metal powder particles provides a scaffold which stabilizes the system …”

Amorphous Mg-based metal foams with ductile hollow spheres

“…The alloy used here has a low glass transition temperature of 157°C and a large supercooled-liquid region ͑crystallization temperature 192°C͒, as measured by differential scanning calorimetry ͑DSC͒ at a rate of 20°C / min. 27 The foams were created by pressure infiltrating the molten alloy into beds of hollow spheres, a method which has been used previously for producing syntactic foam materials from various crystalline alloys [28][29][30][31] and one Zr-based amorphous metal. 32 In the present work, we used iron hollow spheres provided by the Fraunhofer Institute ͑Dresden, Ger-many͒.…”

Highly porous metals and ceramics

“…Metal matrix syntactic foams show great promise for crush energy absorption, 91 while applications for carbon matrix syntactic foams are heat sinks, power electronics cooling and aircraft brake pads. 92 In Fig. 1, images of highly porous metal and ceramic components are presented as examples, showing that very different morphologies can be obtained by employing the various processing methods described previously.…”
