Collaborative Research Center SFB 799:TRIP-Matrix-Composites Design of tough, transformation-strengthened composites and structures based on Fe-ZrO2
Planned program period: 2008 – 2020Coordinator: Prof. Dr.-Ing. habil. Horst Biermann, Institute of Materials Technology, TU BAFDeputy Coordinator: Prof. Dr.-Ing. habil. Christos G. Aneziris, IKGB, TU BAF
The vision of the SFB 799 is the exploration of a new class of high-performance composites calledTRIP-MATRIX-COMPOSITES based on TRIP-assisted steels and zirconium dioxide ceramics (TRIP:transformation-induced plasticity). The development of innovative materials, structures, andprocesses as well as the application of bionic principles to micro and macro structures enable thegeneration of high-performance, highly stressable components with pioneering characteristics forthe passenger safety in cars, trains and aircrafts.www.tu-freiberg.de/ze/sfb799
Priority Programme SPP 1418:Refractories – Initiative to Reduce Emissions – FIRE
Planned program period: 2009 – 2015Coordinator: Prof. Dr.-Ing. habil. Christos G. Aneziris, IKGB, TU BAF
The German Research Foundation (DFG) has triggered a Priority Programme SPP 1418 for the next6 years for applicable basic research in the refractory area by bridging different material disciplinesand understanding the refractory materials as multifunctional, active, advanced ceramic compo-nents. Main targets are lower emissions at high temperature applications due to the impact of re-fractory innovations, development of improved thermal shocked oxide materials and designs as wellas functionality in the application area of steel metallurgy and energy sector.www.tu-freiberg.de/ze/fire
GLASING
Planned program period: 2007 – 2016Coordinator: Prof. Dr.-Ing. Heiko Hessenkemper, IKGB, TU BAF
The aim of the GLASING project is the development of energy efficient technology suitable for theproduction of thermal toughened glass with a thickness of less than 2 mm and improved chemicaland optical properties. The level of tension in the glass should reach that of toughened safety glass.For the thermal toughening of thin glass the heat transmission between glass and cooling mediumhas to be increased considerably. This can be accomplished by employing a liquid phase or agas/liquid phase as a cooling medium. In order to apply this intensified cooling process to the indu-strial thermal toughening of glass, the strength of the glass sheets has to be increased by differentmeans.www.glasing.info
