The present invention concerns the manufacture of bars, wires or profiled elements by hot transformation which may be followed by cold transformation. The invention particularly concerns a new process for the manufacture of a composite billet for hot transformation as well as a method for the manufacture of products which are difficult to transform by making use of such a composite billet.

Composite billet for hot transformation

A revolving anode for an X-ray tube comprising a hollow rotating shell including a support composed of molybdenum or molybdenum-based alloy and a thin layer of tungsten, the shell being filled with liquid metal or alloy such as sodium. The zone of impact of the electrons on the shell essentially comprises the layer of tungsten or tungsten alloy in direct contact with the liquid metal.

Revolving anode for an X-ray tube filled with liquid metal

A rotating anode for an x-ray tube, comprising a body of sintered, molybdenum-based alloy coated with a layer of tungsten or tungsten alloy at least in the zone of impact of the electrons. The molybdenum-based alloy contains from 3 to 10% by weight of tungsten and 0.01 to 0.5% of ZrO.sub.2. The anode has improved resistance to thermal stresses.
