Summary:Embodiments of a turbine nozzle (20) are provided, as are embodiments of methods for the manufacture of turbine nozzles. In one embodiment, the turbine nozzle includes a support ring (60) and a slip joint ring (62), which is substantially concentric with the support ring and radially spaced apart therefrom. The slip joint ring has a plurality of slots (78) therein. A plurality of vanes (64) is fixedly coupled to the support ring and extends radially therefrom into the plurality of slots. A plurality of radial slip joints is formed between the plurality of vanes and the plurality slots. Each slip joint extends around a different one of the plurality of vanes to permit relative radial movement between the plurality of vanes and the slip joint ring during operation of the turbine nozzle.
