abstract = {Industrial pure tungsten grades, manufactured by using a
variety of manufactured techniques, are available worldwide
in many different types of semifinished products, i.e. rods,
wires, ribbons, and sheets. Thereby, the recrystallization
temperature varies depending on the applied degree of
deformation but also depending on the materials composition,
i.e. the materials purity and in particular the level of
certain impurities.In order to compare different available
industrial tungsten grades and a newly developed PIM-W
grade, on the one hand recrystallization studies at three
different temperatures from 1573 to 2073 K for 1 h were
performed using microstructural analyses and Vickers
hardness testing. On the other hand, the thermal shock
induced low cycle thermal fatigue response of the material
in its different recrystallization stages was done using
high heat flux tests at 1273 K base temperature, applying
1000 shots with 1 ms and 0.38 GW/m2 and post-mortem
characterization, i.e. profilometry and metallography. The
obtained results are related to the microstructural and
mechanical features of the materials as well as the chemical
composition of the individual tungsten grades.},
