| 摘要 |
The invention relates to an axial-flow thermal turbomachine having a metallic rotor ( 1 ), in which rotor blades ( 3 ) made of an intermetallic compound are mounted in a circumferential groove to form a row of blades. The invention is characterized in that at least two rotor blades ( 3 ') which are at a uniform distance from one another and are made of a more ductile material are arranged in the said row of blades between the intermetallic rotor blades ( 3 ), the rotor blades ( 3 ') made of the more ductile material either being considerably longer than the intermetallic blades ( 3 ) or, if they are of the same length, having a different blade tip shape than the intermetallic blades ( 3 ).
