The turbine blade has an internal space through which a coolant fluid is guided and in which stiffening ribs are formed to reinforce and support the external walls. Coolant screens that reduce the cooling of the stiffening ribs, are arranged in front of the stiffening ribs in order to reduce thermal stresses. The turbine blade is preferably a gas turbine blade.

Turbine blade

A turbine blade, in particular a gas-turbine blade, which extends along a main axis from a root region over a blade body region to a tip region. The turbine blade has a cavity in the blade body region, at least regions of the cavity being surrounded by a blade wall having a small wall thickness. The blade wall is formed of a metallic material having a small average grain size. In addition, a method of producing the turbine blade is further disclosed.
