| Abstract Scope |
Tantalum-tungsten (Ta-W) alloys are selected for many applications where maintaining strength and ductility during and after a broad range of thermal and environmental exposures is important. Some such environments include exposure to neutron irradiation. The majority of available literature has focused on behavior resulting from exposure levels of 1015-1026 n/cm2, however limited work has been done on lower fluence levels. The focus of this work was to understand the effect of lower (1013-1015 n/cm2) fluence level exposures on the tensile properties of Ta-10W at test temperatures of up to 300°C. The fracture surfaces of tested specimens were characterized using light optical microscopy (LOM) and scanning electron microscopy (SEM).
