Abstract (en)
[origin: WO2004038056A1] 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.
