An X-ray target material comprising an oxide-dispersion strengthened Mo (ODS-Mo) alloy. ODS-Mo refers to molybdenum strengthened by a fine dispersion of insoluble oxide particles of one or more of the following compounds: La2O3, Y2O3 and CeO2. ODS—Mo alloy improves upon the prior art by providing higher and more uniform strength and creep resistance over the applicable temperature range of large brazed graphite targets. This, in conjunction with higher-strength graphite, allows the target to spin faster without causing graphite burst, thus providing improvement in peak power. The recrystallization temperature of the fabricated material is high enough to maintain original properties through all target processing, including a very high-temperature braze cycle.
An X-ray tube anode comprising a target substrate made of oxide-dispersion strengthened molybdenum alloy and a metal track formed on said target substrate and comprising X-ray emitting metal.
An apparatus comprising a substrate made of oxide-dispersion strengthened molybdenum alloy and a metal track formed on said substrate and comprising X-ray emitting metal, wherein said substrate has a generally circular outer periphery and a central hole, and said track is generally annular and concentric with said outer periphery of said substrate.
A method of manufacturing an X-ray tube anode, comprising the following steps:
An anode assembly for an X-ray tube, comprising a rotating disc target and a rotor that is part of a motor assembly that spins said target, wherein said disc target comprises a target substrate made of oxide-dispersion strengthened molybdenum alloy and a metal track formed on said target substrate and comprising X-ray emitting metal.
A method of manufacturing an X-ray tube anode, comprising the following steps:
