A turbine engine includes a turbine driven by hot gas, a compressor rotating with the turbine to generate compressed air, an annular combustor coaxial with the turbine to combust fuel and compressed air to generate the hot gas, and an annular recuperator to recover heat from the turbine exhaust gas and heat the compressed air for combustion. The annular recuperator surrounds the turbine and includes two contiguous parts made from two materials having different thermal properties and joined to one another to form a single annular structure. One recuperator part is formed from a high-temperature material having a high thermal limit for exposure to high-temperature turbine exhaust gas, and the other recuperator part is formed from a material having a lower thermal limit than the high-temperature material for exposure to reduced-temperature turbine exhaust gas.
