Abstract (en)

[origin: EP2210688A1] The component e.g. turbine blade (120) comprises a first region such as a blade region (406), and a second region such as a blade fastening region (400), which has a downwardly arranged structure opposite to the first region, where a blade platform (403) is used as first and/or second regions. A stalk-shaped structure and an undirected rigid structure represent the downwardly arranged structure opposite to a monocrystalline structure (SX). The undirected rigid structure represents a secondary structure opposite to the stalk-shaped structure and the monocrystalline structure. The component e.g. turbine blade (120) comprises a first region such as a blade region (406), and a second region such as a blade fastening region (400), which has a downwardly arranged structure opposite to the first region, where a blade platform (403) is used as first and/or second regions. A stalk-shaped structure and an undirected rigid structure represent the downwardly arranged structure opposite to a monocrystalline structure (SX). The undirected rigid structure represents a secondary structure opposite to the stalk-shaped structure and the monocrystalline structure. The entire blade region or the first region has stalk-shaped structure or monocrystalline structure. The monocrystalline structure and the stalk-shaped structure extend up to a certain thickness but partially into the blade platform and/or extend through the entire blade platform. The blade fastening region has undirected rigid structure or stalk-shaped structure. The blade platform has further structure than the blade region and/or same structure as the blade region. The second region contains additional alloy than in the first region. An independent claim is included for a method for producing a component.
