Interlocking ceramic elements lead to quasi-plastic properties

By Martin Grolms / May 29, 2012

Display of self-interlocking elements from oxide ceramics. Assemblies of such elements possess an increased bending compliance compared to bulk plates. Cracks are confined to a few elements, so that most of the elements stay intact and are reusable. Credit: T. Krause et al.; Adv. Eng. Mater. For many high-temperature applications, ceramics are indispensable. No other…

Video of the week: Ultrahigh-temperature ceramics and hypersonic flight

By / March 31, 2010

[flash https://ceramics.org/ceramictechtoday/wp-content/video/hilmas_fahrenholtz.flv mode=1 f={image=/ceramictechtoday/wp-content/video/hilmas_fahrenholtz.jpg}] Greg Hilmas and Bill Fahrenholtz, both professors at Missouri S&T, are working on developing ceramic materials that can withstand ultrahigh temperatures (1,600°C–3,000°C) that will be encountered by hypersonic planes of the future. Ultrahigh-temperature ceramic materials are particularly needed on the leading edges of acute flight surfaces to withstand the intense heat…
