TURBINE BLADE AND A METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a turbine blade (1) which extends along a principal axis (2) of a foot area (3) up to a head area (5) via a blade area (4). A feed (6) for cooling liquid (16) is provided in the blade area (4), said feed being surrounded by a thin outerwall (7) of the blade. The outer wall (7) of the blade consists of a metal material with a nondirectional granular structure of an average grain size with the dimensions of the grain size of a conventionally cast material. The invention also provides for a method for producing a turbine blade.
