Abstract
A target for generating x-rays includes a target substrate comprising at least one layer of a target material, a track comprising at least one layer of a track material, the track configured to generate x-rays from high-energy electrons impinging thereon, and a braze joint attaching the target substrate to the track.

A method of fabricating an x-ray target assembly compnsing:
- 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 disperse the initial joint material into at least one of the substrate and the track to form a final joint therebetween;
- wherein the track material comprises a wrought alloy.
