Description
In this dissertation, two topic areas related to adiabatic shear banding (ASB) phenomenon were studied. Body centered cubic (BCC) metals and alloys may exhibit ASB under uniaxial high strain rate compression if the grain size is refined into the u...

Description
Tungsten and tantalum are neighbors in the Periodic Table of the Elements and, as refractory metals, both have very high melting points (tungsten: 3422oC, tantalum: 2996oC). However, the ductility of the two metals is quite different especially at...
