Compressor, preferably a high-pressure compressor of a gas turbine, comprises at least one integrally bladed rotor made of a disk (2) and many blades (3), which are disposed on the disk, where the integrally bladed rotor comprises at least one titanium material comprising titanium-6246 and titanium-6242. The materials of the disk and the blades differ in their chemical composition and/or their micro-structure. Independent claims are also included for: (1) an integrally bladed rotor with the disk and many blades disposed on the disk, where the integrally bladed rotor has at least one titanium material comprising titanium-6246 and titanium-6242, and the materials of the disk and the blade differ in their chemical composition and/or their micro-structure; (2) producing an integrally bladed rotor, preferably for a compressor, comprising welding the blades to the disk by a pressure welding method supported by high-frequency current, where the current is conducted through the joint surfaces and leads to local melting of surfaces, and providing a disk, which is formed from titanium-6246 or lamellar titanium-6246 for the welded joint (4), and forming the blades from titanium-6242 or bimodal titanium-6246; and (3) a gas turbine with integrally bladed rotor. |
