The invention relates to a blade cascade for a turbomachine, having a number of blades (11, . . . 14; 21, . . . 25; 31, . . . 37) which include a monocrystalline material, each blade having a crystal orientation value (|α|), which is dependent on a crystal of first blades (11, . . . 14) being less than a first limiting value and the crystal orientation values of second blades (21, . . . 25; 31, . . . 37) being at least equal to the first limiting value; and the blade cascade having at least one first sector (1), which includes at least three successive first blades (14, 12, 11, 13), and having at least one second sector (2+3; 2′+3′; 2″+3″), which includes at least three successive second blades (22, 21, 23, 24, 25; 31, 34, 36, 37, 33, 32, 35; and/or at least one first blade has a first body arrangement having at least one first body mounted so it is movable on the first blade and at least one second blade has a second body arrangement, which differs therefrom, having at least one second body mounted so it is movable on the second blade. |
