Abstract
This paper presents a method for identifying the crystal orientation o f single crystals with cubic crystal structure based on a conventional resonance measurement and a FE-analysis. It includes a non-linear opt imizer, an FE-program for solving eigenvalue equations, and a frequenc y assignment algorithm. This method provides an independent verificati on or an alternative to the Laue x-ray method. The results for two fcc Ni-base superalloy single crystals demonstrate the efficiency and eco nomy of this method.
