摘要:
The invention relates to a blade (1) for a turbine engine (41) with a base body (2), made from a titanium alloy, with a first and a second component piece (11,13), which are connected in a connection region (31) by means of a bonding process. A groove (23) with a groove wall (27) runs through the connection region (31), to prevent local concentration of tension, such that the above borders directly on the second component piece (13) and forms therewith a connection angle (α) greater than 70 degrees.
