摘要：
Commercially pure vanadium was processed by high pressure torsion at room temperature into the saturation regime and investigated with respect to the microstructure and resulting mechanical properties. Besides hardness, strength and ductility special emphasis was put towards the fracture toughness after processing. The results demonstrate, so far unusual for pure ultrafine-grained body-centered cubic metals, remarkable ductility and fracture toughness while also having high strength. (C) 2015 Elsevier B.V.
