A unique gold-silver alloy specimen, the so-called "Ram's Horn" with an unusual wire morphology, was characterized by multiple unique non-destructive methods at LANL: Neutron resonance absorption imaging provided elemental distribution, hard X-ray CT (using the spallation gamma flash by blocking the neutron beam on the same beamline as well as with a microtron source) to characterize density variations, and time-of-flight neutron diffraction to obtain spatially resolved microstructural characterization. The goal was to understand the origin of this unique specimen better, e.g. by comparing the microstructure with that of similar wire silver.
