ABSTRACT:
This invention provides a molybdenum alloy having excellent high-temperature strength, an X-ray tube rotary anode target having high-temperature strength, an X-ray tube, and a melting crucible. The molybdenum alloy, having an oxygen content of not more than 50 ppm, comprising 0.2 to 1.5% of a carbide by weight and the balance, molybdenum, wherein the carbide is at least one selected from titanium carbide, hafnium carbide, zirconium carbide, and tantalum carbide, and a part of the carbides has an aspect ratio of not less than 2.
