Abstract
Heat treatment of alloys having elements for improving grain boundary strengthComponents 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.
