Abstract (en)
[origin: EP0574708A1] The component is intended for use at high temperatures and is designed especially as a turbine blade. It contains a component body comprising at least a first section (blade root 3) and a second section (blade leaf 2). The first section (3) is formed from a ductile material. However, the second section (2) is of a material which is brittle as compared with the ductile material. It is intended that this component is distinguished by a long service life. This is achieved in such a way that each of the two materials contains in each case one of two alloys based on a common principal material and of different chemical compositions, which differ from one another by the presence and/or the quantity of at least one doping substance alloyed with the principal material. <IMAGE>
