However, the intrinsic brittleness of tungsten is an issue under the extreme fusion environment. To overcome this drawback, tungsten fiber-reinforced tungsten (Wf/W) composites are being developed relying on an extrinsic toughening principle. In this study Wf/W composites are produced by a Field-Assisted Sintering Technology (FAST) process with different fiber–matrix interfaces. The fracture behavior was studied by 3-point bending tests on notched samples. 4-point bending tests and tensile tests are performed to measure the flexural strength and tensile strength, respectively. Wf/W with a weak interface shows a typical pseudo-ductile fracture behavior, similar to ceramic matrix composites. A strong interface is beneficial to achieve higher flexural strength and tensile strength, but in turn, weakens the pseudo-ductile behavior.}, cin = {IEK-4}, ddc = {660}, cid = {I:(DE-Juel1)IEK-4-20101013}, pnm = {113 - Methods and Concepts for Material Development (POF3-113)}, pid = {G:(DE-HGF)POF3-113}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000429892800036}, doi = {10.1016/j.compositesa.2018.01.022}, url = {https://juser.fz-juelich.de/record/891434}, }
