abstract = {Since the ITER divertor design includes tungsten monoblocks
in the vertical target where heat loads are maximal, the
design to protect leading edges as well as technology $R\&D$
for high performance armor-heat sink joint were necessary to
be implemented. In the $R\&D,$ the availability of the
technology was demonstrated by high heat flux test of
tungsten monoblock components. Not systematically but
frequently macro-cracks appeared at the middle of monoblocks
after 20 MW/m2 loading. The initiation of such macro-cracks
was considered to be due to cyclic exposure to high
temperature, ∼2000 °C, where creep, recrystallization and
low cycle fatigue were concerned. To understand correlation
between the macro-crack appearance and mechanical properties
and possible update of acceptance criteria in the material
specification, an activity to characterize the tungsten
monoblocks was launched.},
