A turbine (1) of a turbine engine comprising a housing (4), a distributor stage (2) of the turbine (1) and a metal ring (5) supporting abradable material (51), the distributor stage (2) being made from ceramic matrix composite material and comprising several annular sectors (20) forming a crown having an internal ferrule (24) and an external ferrule (26), each sector (20) having an internal platform (24) forming a part of the internal ferrule (240), an external platform (26) forming a part of the external ferrule (260), and at least one blade (28) extending between the external platform (26) and internal platform (24) and rigidly connected to said platforms, the metal ring (5) comprising at least one annular sector. The metal ring (5) has an outer surface (56e) in contact with the surface (24i) of the internal ferrule (240) opposite the surface (24e) from which the blades (28) extend, the metal ring (5) having, on the outer surface (56e) of same, an outer diameter greater than the diameter of the internal ferrule (240), such that the distributor stage (2) is held compressed between the housing (4) and the metal ring (5). |
