Journal ArticleDOI
In situ synchrotron tomography estimation of toughening effect by semi-ductile fibre reinforcement in a tungsten-fibre-reinforced tungsten composite system
Johann Riesch,Jean-Yves Buffiere,Till Höschen,M. Di Michiel,Mario Scheel,Ch. Linsmeier,J.-H. You +6 more
TL;DR: In this article, single-fibre tungsten composite specimens are fabricated and the stress-strain behaviour of the tungststen fiber bridging a matrix crack is measured by means of in-situ high energy synchrotron micro-tomography during an uniaxial tension test.
Journal ArticleDOI
Materials for DEMO and reactor applications—boundary conditions and new concepts
J. W. Coenen,Steffen Antusch,M. Aumann,Wolfgang Biel,Wolfgang Biel,J. Du,J. Engels,S. Heuer,A. Houben,T. Hoeschen,B. Jasper,Freimut Koch,Jochen Linke,Andrey Litnovsky,Yiran Mao,R. Neu,R. Neu,Gerald Pintsuk,Johann Riesch,Marcin Rasinski,J. Reiser,Michael Rieth,Alexis Terra,B. Unterberg,Th. Weber,T. Wegener,J.-H. You,Ch. Linsmeier +27 more
TL;DR: In this article, composites as well as strengthened CuCrZr components together with oxidation resilient tungsten alloys allow the step towards a fusion reactor to be taken. But the first stage prototype fusion reactor is considered to be the next step after ITER towards realizing fusion.
Journal ArticleDOI
Melt infiltrated tungsten–copper composites as advanced heat sink materials for plasma facing components of future nuclear fusion devices
Alexander Müller,Alexander Müller,Daniel Ewert,Andrei Galatanu,M. Milwich,R. Neu,R. Neu,Jose Ygnacio Pastor,U. Siefken,E. Tejado,J.-H. You +10 more
TL;DR: In this article, the authors summarise recent results regarding the manufacturing and characterisation of such W-Cu composite materials produced by means of liquid Cu melt infiltration of open porous W preforms.
Journal ArticleDOI
The thermo-mechanical behaviour of W-Cu metal matrix composites for fusion heat sink applications: The influence of the Cu content
TL;DR: In this article, the thermal properties of W-Cu composites with 15, 30 and 40% Cu were investigated and the microstructure, thermal properties, and mechanical performance were investigated from RT to 800°C.
Journal ArticleDOI
Issues and strategies for DEMO in-vessel component integration
C. Bachmann,Frederik Arbeiter,Lorenzo Virgilio Boccaccini,M. Coleman,G. Federici,Ulrich Fischer,R. Kemp,F. Maviglia,Giuseppe Mazzone,Pavel Pereslavtsev,R. Roccella,N. Taylor,Rosaria Villari,Fabio Villone,Ronald Wenninger,J.-H. You +15 more
TL;DR: The design and technology limitations of IVCs, their consequences on the integration principles, and strategies currently considered in the DEMO tokamak design approach are identified.
