ABSTRACT:
The invention relates to a turbine blade (31) having a root region (33), a tip region (37) and a blade airfoil (35), a rounded portion (73) being formed between the root region (33) and the blade airfoil (35), and relief slots (51) passing through the blade trailing edge (41) in the region of this rounded portion (73), thermal expansions being compensated for and thus thermal stresses being minimized by these relief slots (51).
