Abstract (en)
A modular vane/blade (20b) for a gas turbine comprises a basic element (18a) made of a first material, which is provided with at least one insert/inlay (21 b) made of a second material, which is integrally joined with said basic element (18a) and has at least one runout (23a-c). An improved mechanical stability and integrity by placing said at least one runout (23a-c) in a region of low mechanical stress within said vane/blade (20b).
