The mechanical test results of manufactured joints are in good accordance with high heat flux test results, showing that the behaviour of hot-pressed joints with W/Fe co-sputtered layer was slightly worse if compared to joints without co-sputtered layer at the interface.}, cin = {IEK-4}, ddc = {624}, cid = {I:(DE-Juel1)IEK-4-20101013}, pnm = {134 - Plasma-Wand-Wechselwirkung (POF4-134)}, pid = {G:(DE-HGF)POF4-134}, typ = {PUB:(DE-HGF)16}, UT = {WOS:001009154300001}, doi = {10.1016/j.nme.2023.101421}, url = {https://juser.fz-juelich.de/record/1008401}, }
