Abstract:
1. A method of fabricating an x-ray target assembly comprising: forming a substrate having at least one layer of substrate material comprising molybdenum or an alloy of molybdenum; positioning a track proximate the substrate, the track having at least one layer of track material configured to generate x-rays from high-energy electrons impinging thereon; positioning an initial joint material between the substrate and the track; and elevating a temperature of the substrate, the track, and the initial joint material to a temperature below a melt temperature of the initial joint material to disperse the initial joint material into at least one of the substrate and the track to form a final joint therebetween, the final joint material having a melt temperature that is greater than a melt temperature of the initial joint material; wherein the track material comprises a wrought alloy.
