    摘要: A rotary anode for a rotary anode X-ray tube has an anode disc with a supporting portion. A focal track is located in the vicinity of an outer diameter of the anode disc. The supporting portion has inhomogeneous material properties along a radial coordinate of the anode disc to provide a high mechanical load capacity in the area of an inner diameter of the anode disc and a high thermal load capacity at the focal track. These measures provide for a rotary anode for a rotary anode X-ray tube that meets the extreme thermal and mechanical loads during operation. Further, a method for manufacturing such a rotary anode is described as well.
