PROBLEM TO BE SOLVED: To provide a method and a device for minimizing temperature gradient in a turbine shroud. SOLUTION: A low-pressure turbine shroud 40 includes a rear plate 42 and a material 90, attached to the rear plate and capable of being ground. The rear plate is provided with an end 44 on the upstream side, an end 46 on the downstream side, and a body 48 extending between the end on the upstream side and the end on the downstream side. The body is provided with a first part 74 and a second part 76. The first part of the main body has a first thickness T1 larger than a second thickness T2 of the second part of the body. The material capable of being ground is attached to the inner surface of the rear plate and has at least one segment 114, having a thickness T5 larger than those of remaining segments 110, 112 of the material capable of being ground. |
