Properties of Ultrafine-Grained Tungsten Prepared by Ball Milling and Spark Plasma Sintering

Popis výsledku v původním jazyce

Tungsten is a candidate material for the first wall of a nuclear fusion reactor. First wall will be subjected to harsh conditions that will gradually deteriorate properties of the wall material. Some studies point out that fine-grained tungsten could bemore resistant to the structure and property changes than coarse-grained tungsten. In this study, preparation of ultrafine-grained tungsten by mechanical processing in a planetary ball mill was examined. Three types of tungsten samples were compared. Onewas made from coarse grained tungsten powder consolidated by SPS (Spark Plasma Sintering). Other two samples were prepared from the powder processed in a planetary ball mill with and without addition of Y2O3. After ball milling, the powders were consolidated by SPS. Properties of the samples such as hardness and thermal conductivity were examined and correlated with the processing history and microstructure.
