An x-ray anode for use in an x-ray tube is provided. The x-ray anode
includes a substrate material, a target material, and one or more graded
coefficient of thermal expansion material layers. The target material is
coupled to the one or more graded coefficient of thermal expansion
material layers and the graded coefficient of thermal expansion material
layers are coupled to the substrate material. A method of making the
x-ray anode is also provided.
