----------- Start Original Message ----------- : I would be interested in talking to anyone who has used Barkhausen Noise techniques for the early detection of creep damage in materials. : Can Barkhausen techniques be used successfully for non destructive evaluation of high grade stainless steels (e.g. hastelloy, 1.4435 etc?) ------------ End Original Message ------------
