| Abstract Scope |
Tantalum-tungsten (Ta-W) alloys exhibit desirable thermal, mechanical, electrical, and corrosion properties, and are often selected for 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 radiation, and available literature has mainly focused on characterizing Ta-W behavior resulting from fluence exposure levels of 1015-1026 n/cm2. The focus of this work is to understand the effects of multiple lower fluence level exposures (1013-1015 n/cm2) on the tensile properties of Ta-W alloys at test temperatures of 25°C - 300°C. The fracture surfaces of tested specimens were characterized using light optical microscopy (LOM) and scanning electron microscopy (SEM).
