Abstract: A turbine component is disclosed. The turbine component includes an outer shroud and an inner shroud having a first hook region extending over a first portion of the outer shroud and a second hook region extending over a second portion of the outer shroud. A first hook gap, a second hook gap, a first radial gap, and a second radial gap are arranged and disposed to permit the inner shroud to deflect from the outer shroud under thermal loading. Additionally or alternatively, the inner shroud includes ceramic matrix composite fibers having a thermal conductivity of less than 200 W/m·k and greater than 10 W/m·k.
