Characteristics of W-26% Re Target Material(LCC-0103)
The W-26 wt-% Re alloy was selected as a Stanford Linear Collider (SLC) target material for its exceptional physics properties and for the high strength and good ductility at the anticipated target operating temperatures, above the DBTT. After several years of operation, the target failed catastrophically. A detailed microstructural and mechanical characterization of the non-irradiated disk indicates that the material has been PM processed, nonuniformly mechanically worked and stress relieved. As a result, the ductility of the material varies through the thickness of the disk, making it difficult to determine the DBTT. The results of tensile and fatigue properties are reported with the corresponding fractography of the fracture surfaces.
