METHOD FOR THE PRODUCTION OF CAST COMPONENTS
Document Type and Number:
WIPO Patent Application WO2005071128
Kind Code:
A3
Abstract:
The invention relates to a method for the production of a cast component, in particular a gas turbine component. 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.
