The turbine shroud of claim 6, wherein the contact feature is a convex wall extending circumferentially along and radially outward from the radially outer surface of the finger. 10. A turbine shroud comprising a plurality of carrier segments comprising metallic materials and arranged circumferentially adjacent to one another around an axis, each carrier segment including a body and a slot formed along a radially inner portion of the body, anda plurality of blade track segments comprising ceramic-matrix composite materials and arranged circumferentially adjacent to one another around the axis, each blade track segment including a runner and at least one attachment post that extends outwardly in a radial direction from the runner,wherein the attachment post of each blade track segment engages with the slot of at least one carrier segment to couple the plurality of blade track segments to the carrier segments, the slot of each carrier segment is formed to include a plurality of circumferentially spaced apart fingers and arranged to be engaged by the attachment posts of the blade track segments, and the fingers are configured to flex inward in the radial direction when engaged by the attachment posts of the blade track segments. 11. The turbine shroud of claim 10, wherein each of the slots includes a circumferentially extending outer wall, a first stop wall extending radially inward from the outer wall, and a second stop wall spaced apart from the first stop wall and extending radially inward from the outer wall, wherein a first portion of the plurality of fingers are positioned along an intersection of the outer wall and the first stop wall and a second portion of the plurality of fingers are positioned along an intersection of the outer wall and the second stop wall, andwherein the first and second portions of the plurality of fingers extending radially inward from the outer wall and toward one another. 12. The turbine shroud of claim 11, wherein each of the fingers includes a free end spaced apart from the first and second stop walls and an engagement surface extending between the outer wall and the free end. 13. The turbine shroud of claim 12, wherein the first and second stop walls are configured to engage with the plurality of fingers to block the plurality of fingers from flexing past the first and second stop walls. 14. The turbine shroud of claim 10, wherein the plurality of fingers are each formed to include a contact feature positioned to contact the attachment posts of the blade track segments. 15. The turbine shroud of claim 14, wherein the contact feature is a lip extending radially outward from a free end of the finger. 16. The turbine shroud of claim 14, wherein the contact feature is a convex wall extending axially along and radially outward from radially outer surface of the finger. 17. The turbine shroud of claim 14, wherein the contact feature is a convex wall extending circumferentially along and radially outward from the radially outer surface of the finger. 18. A method of assembling a turbine shroud comprising arranging a plurality of carrier segments comprising metallic materials circumferentially adjacent to one another around an axis, each carrier segment including a body and a bracket that extends inwardly in a radial direction from the body toward the axis, arranging a plurality of blade track segments comprising ceramic-matrix composite materials circumferentially adjacent to one another around the axis, each blade track segment including a runner and at least one hanger that extends outwardly in the radial direction from the runner, andengaging the hangers of the blade track segments with the brackets of the carrier segments to couple the blade track segments with the carrier segments,wherein the bracket of each carrier segment is formed to include a plurality of circumferentially spaced apart fingers extending generally axially from the body and arranged to be engaged by the hangers of the blade track segments, and the fingers are configured to flex inward in the radial direction when engaged by the hangers of the blade track segments.
