摘要： The invention relates to a method for repairing components (1) comprising a base material with an oriented microstructure, wherein the repair point (3) comprises a correspondingly oriented microstructure as the surrounding base material. According to the inventive method, solder (7) is applied in the region of a point (3) which is to be repaired and is soldered to the component (1) by means of a heating effect produced by a device (9). A temperature gradient, i.e, approximately a temperature characteristic, is produced during the heating effect, said temperature characteristic ranging from a high to a low temperature in the region of the point (3) which is to be repaired.

摘要： The invention relates to a guide blade segment (2) of a thermal turbomachine, in particular a gas turbine, comprising a number of profiled blades (6) which are arranged on a platform (8). A plurality of securing elements (14) for securing the guide blade segment (2) to an associated guide blade support are arranged on the side of the platform (8) which is oriented away from the blade(s). The aim of the invention is to provide a guide blade segment (2) which can be produced in a simple and economical manner avoiding casting problem areas enabling the guide blade segment to be attached in a particularly reliable and secure manner to the associated guide blade support. According to the invention, at least one section of at least one of the securing elements (14) is a separately produced component which is rigidly connected to the platform (8) or to an additional section of the securing element (14).

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.

摘要： Heat treatment of alloys having elements for improving grain boundary strength. Components directly after castings often reveal a low or no transverse grain boundary strength, so that cracks do appear and decrease the yield rate. The inventive measures does not lead to low transverse grain boundary strength but maintains a efficient grain boundary strength, so that the yield rate of components without cracks is increased.

摘要： The invention relates to a method for the production of a pattern for precision casting representation of a turbine component comprising at least one cavity, whereby the prepared pattern comprises at least one core and an outer contour pattern (1), at least partly enclosing the core and at least partly defining the outer contour of the turbine component. The core is made from a hardening core material (11), which hardens during the course of the method and the outer contour pattern (1) is made from a combustible or fusible material. The outer contour model (1) is first produced with at least one cavity (8a-8e) corresponding to the at least one cavity of the turbine component and subsequently, in order to form the at least one core, the hardening core material (11) is introduced into the at least one cavity (8a-8e) and hardened.
