A shroud hanger assembly for components formed of materials having differing coefficients of thermal expansion, comprising: an engine casing; a multi-piece hanger assembly formed of a first material, said multi-piece hanger assembly having a forward hanger portion and a rearward hanger portion, said multi-piece hanger assembly connected to said engine casing; a shroud formed of a low coefficient of thermal expansion second material different from said first material, said shroud disposed in a cavity between said forward hanger portion and said rearward hanger portion; at least one cooling channel extending into said forward hanger portion of said shroud hanger assembly for impingement cooling of said shroud; a conformal seal extending between and acting on the rearward hanger portion and the shroud, and characterized in that the forward hanger portion includes a tab for engagement with said engine casing, and a radially extending leg depending from the tab, said leg comprising a lower portion having a radially lower end, said lower end axially engaging the shroud at a forward end of said shroud; wherein the forward hanger portion further includes a web extending from the leg toward the rearward hanger portion, wherein the web comprises a web tab at an aft end of the web, said web tab being received in an axial direction by a web tab receiving slot in the rearward hanger portion; wherein the rearward hanger portion includes a first tab positioned within a receiving groove of the engine casing, said rearward hanger portion extending in a circumferential direction defining a segment having a circumferential length, said rearward hanger portion comprising a lower portion extending radially below the web tab receiving slot, the lower portion being generally U-shaped and the U-shaped lower end axially engages the shroud at an aft end of said shroud providing a biasing force on the shroud, so that the rearward hanger portion functions as a spring leg to provide an axial interference force on the shroud; wherein the web tab of the forward hanger portion web engages the rearward hanger portion within said web tab receiving slot and the rearward hanger portion first tab engages the engine casing, so that the rearward hanger portion is sandwiched against the engine casing by the forward hanger portion and axially captured between the forward hanger portion and the engine casing; the conformal seal engaging the lower portion of the rearward hanger portion and extending between an inside curvature of the U-shaped lower portion and an aft surface of the shroud, the conformal seal being curvilinear and configured to provide a biasing force acting against the aft surface of said shroud in the axial direction. an engine casing;
