Development of nanostructured W and WL10 by high-pressure torsion

Wang, Yiming

Abstract:
Nanostructured W and WL10 are fabricated by high-pressure torsion. Grains are refined from initial coarse range (10µm) to nanometers scale (80nm-400nm). Influences of original microstructure, alloying, process temperature and strain path are investigated. Thermal stability and room temperature fracture toughness of deformed materials are evaluated as well. Microstructure, texture and hardness are measured by scanning electron microscopy, electron backscatter diffraction and nanoindentation.
