The studies described by Langenberg et al. have very strongly enhanced the interpretation of propagation of elastic waves also in anisotropic and inhomogeneous media we have in practice, for instance, in welds of austenitic stainless steels or dissimilar metal (Ni-alloys) welds in the nuclear and chemical industries." -- Gerd Dobmann, Fraunhofer-IZFP, Saarbrcken, Germany "... absolutely a must for every scientist who would like to further evaluate theoretically ultrasonic NDT.
