Turbine wheel and method of manufacturing the same

A turbine wheel comprises a shroud component (10) and a bladed disc component (20). The shroud component comprises a shroud structure(ll), a hub structure (12) and at least one spoke (13a- f) formed integrally therewith and extending between the shroud structure and the hub structure. The bladed disc component comprises a hub member (21) having an outer rim (22), one or more turbine blades (23) disposed on the outer rim. The shroud component and the bladed disc component provide the turbine wheel with a shrouded portion. A shrouded turbine wheel can therefore be conveniently assembled starting from at least two components as described herein. Further, these components have simplified geometries whereby they can now also be easily manufactured, for example using a casting technique, while the overall mechanical performance of the turbine wheel is preserved or improved.
