abstract = {Functionally graded (FG) iron/tungsten (Fe/W) composites
are considered for stress-relieving interlayers in
tungsten-steel joints, required in future fusion reactors.
The macroscopic gradation of the two materials allows
relaxation of thermally-induced stresses and hence extend
the lifetime of the cyclic-loaded dissimilar materials
joints. While many properties, e.g. thermal expansion and
strength, of the as-manufactured Fe/W composites are
promising with respect to the anticipated application, the
temperature-induced microstructural changes and their effect
on the material properties remain largely unexplored. Given
that the thermodynamic system of Fesingle bondW contains two
types of intermetallic phases, understanding the
microstructural changes in the FG Fe/W composites is crucial
for long-term operation of fusion reactors.},
