The inventive method comprises at least the following steps: a) a crucible and at least one semi-finished product is prepared from an intermetallic titanium-aluminium material; b) the or each semi-finished product made of intermetallic titanium-aluminium material is melted in the crucible; c) at least one additional element or an additional compound is added to the melt, whereby the or each element and/or the or each compound is introduced into the melt according to the melting temperature thereof; d) a casting mould is prepared; e) the casting mould is filled with the melt; f) the melt is solidified in the casting mould; g) the casting component is extracted from the casting mould.
摘要:
A structural component is formed with an outer shell of sintered, solid, powder particles, and a porous core of sintered, hollow, bodies arranged in layers. The hollow bodies are of increased diameter in the layers in a direction from the outer periphery of the core towards the center of the core. The material of the outer shell and of the core is a metal or ceramic.
摘要:
A component for a gas turbine, especially a blisk or a bling, whereby the component includes a rotor base (12) made of a high temperature-resistant nickel alloy and a plurality of turbine blades (14) joined to the rotor base, whereby each turbine blade includes a rotor blade (16) made of a titanium alloy and a blade root. The blade root is configured as an adapter element (18) that is made of a material that can be welded to the titanium alloy as well as to the high temperature-resistant nickel alloy and that is integrally joined to the rotor base (12) and to the rotor blade (16) fusion. A method for the production of the component is also described.
