Abstract
A new method for forming a joint between a molybdenum-based alloy structure and a structure formed from a more ductile alloy is disclosed. The method involves the solid-state bonding of the two structures, which can be carried out by a variety of techniques, such as inertia-welding or explosive-welding. The molybdenum-based alloy may be a TZM-type material, while the more ductile alloy may be tantalum-based, niobium-based, or nickel-based, for example. This method is especially useful in the manufacture of x-ray devices, such as those which include rotary anode assemblies. As one illustration, the method can be used to provide a very strong joint between a target formed from a molybdenum alloy and an insert formed from a tantalum alloy. Related x-ray assemblies are also described.
