abstract = {This work reports about preparation of W/Fe co-sputtered
layers between tungsten and steel in order to ease their
coefficient of thermal expansion mismatch.Iron and tungsten
have been gradually co-sputtered on W tiles with real time
deposition parameters changing to obtain a graded
interlayer: SEM, EDS, XPS, HR-TEM have been used to
characterize the W/Fe co-sputtered layer.W tiles
co-sputtered with the W/Fe layers have been hot pressed to
steel tiles: morphology and mechanical strength have been
investigated for joints with and without W/Fe co-sputtered
layer.Lap-shear tests in compression at room temperature
have been made on hot pressed W/steel joints with and
without W/Fe co-sputtered layer, showing a different
behaviour.High flux test on joints with and without W/Fe
co-sputtered layer are reported and discussed. 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.},
