Influence of an Ultrafine-Grained Structure on the Formation of Blister under High-Fluence Irradiation of Tungsten with 30-keV He+ Ions
摘要
Abstract
The influence of an ultrafine-grained tungsten structure with an average grain size of 300 nm on the formation of blisters on the surface under high-fluence irradiation by 30-keV He+ ions has been studied. Fine-grained tungsten has been used for comparative studies. The microstructure and surface morphology of the samples have been investigated.
