These mechanisms allow the release of stress peaks and thus improve the materials resistance against crack growth. Wf/W samples produced via chemical vapor infiltration (CVI) indeed show higher toughness in mechanical tests than pure tungsten. By utilizing powder metallurgy (PM) one could benefit from available industrialized approaches for composite production and alloying routes. In this contribution the PM method of hot isostatic pressing (HIP) is used to produce Wf/W samples. A variety of measurements were conducted to verify the operation of the expected toughening mechanisms in HIP Wf/W composites. The interface debonding behavior was investigated in push-out tests. In addition, the mechanical properties of the matrix were investigated, in order to deepen the understanding of the complex interaction between the sample preparation and the resulting mechanical properties of the composite material. First HIP Wf/W single-fiber samples feature a compact matrix with densities of more than 99% of the theoretical density of tungsten. Scanning electron microscopy (SEM) analysis further demonstrates an intact interface with indentations of powder particles at the interface-matrix boundary. First push-out tests indicate that the interface was damaged by HIPing. 000256355 536__ $$0G:(DE-HGF)POF3-174$$a174 - Plasma-Wall-Interaction (POF3-174)$$cPOF3-174$$fPOF III$$x0 000256355 536__ $$0G:(DE-Juel1)HITEC-20170406$$aHITEC - Helmholtz Interdisciplinary Doctoral Training in Energy and Climate Research (HITEC) (HITEC-20170406)$$cHITEC-20170406$$x1 000256355 588__ $$aDataset connected to CrossRef 000256355 7001_ $$0P:(DE-Juel1)2594$$aCoenen, Jan W.$$b1$$ufzj 000256355 7001_ $$0P:(DE-HGF)0$$aRiesch, Johann$$b2 000256355 7001_ $$0P:(DE-HGF)0$$aHöschen, Till$$b3 000256355 7001_ $$0P:(DE-Juel1)129591$$aBram, Martin$$b4$$ufzj 000256355 7001_ $$0P:(DE-Juel1)157640$$aLinsmeier, Christian$$b5$$ufzj 000256355 773__ $$0PERI:(DE-600)2047372-2$$a10.4028/www.scientific.net/MSF.825-826.125$$gVol. 825-826, p. 125 - 133$$p125 - 133$$tMaterials science forum$$v825-826$$x1662-9752$$y2015 000256355 8564_ $$uhttps://juser.fz-juelich.de/record/256355/files/MSF.825-826.125.pdf$$yRestricted 000256355 909CO $$ooai:juser.fz-juelich.de:256355$$pVDB 000256355 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)158038$$aForschungszentrum Jülich GmbH$$b0$$kFZJ 000256355 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)2594$$aForschungszentrum Jülich GmbH$$b1$$kFZJ 000256355 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129591$$aForschungszentrum Jülich GmbH$$b4$$kFZJ 000256355 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)157640$$aForschungszentrum Jülich GmbH$$b5$$kFZJ 000256355 9131_ $$0G:(DE-HGF)POF3-174$$1G:(DE-HGF)POF3-170$$2G:(DE-HGF)POF3-100$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bEnergie$$lKernfusion$$vPlasma-Wall-Interaction$$x0 000256355 9141_ $$y2015 000256355 915__ $$0StatID:(DE-HGF)0010$$2StatID$$aJCR/ISI refereed 000256355 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR 000256355 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000256355 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000256355 9201_ $$0I:(DE-Juel1)IEK-1-20101013$$kIEK-1$$lWerkstoffsynthese und Herstellungsverfahren$$x0 000256355 9201_ $$0I:(DE-Juel1)IEK-4-20101013$$kIEK-4$$lPlasmaphysik$$x1 000256355 980__ $$ajournal 000256355 980__ $$aVDB 000256355 980__ $$aI:(DE-Juel1)IEK-1-20101013 000256355 980__ $$aI:(DE-Juel1)IEK-4-20101013 000256355 980__ $$aUNRESTRICTED 000256355 981__ $$aI:(DE-Juel1)IFN-1-20101013 000256355 981__ $$aI:(DE-Juel1)IMD-2-20101013 000256355 981__ $$aI:(DE-Juel1)IEK-4-20101013
