Abstract
According to one embodiment, there is provided an X-ray tube target. The X-ray tube target has a structure in which a carbon base material is bonded with an Mo base material or Mo alloy base material with a joint layer. The joint layer includes an MoNbTi diffusion phase, an NbTi alloy phase, an Nb-rich phase and a ZrNb alloy phase when the ratios of components in the joint layer are detected by EPMA.
