Hi, I'm looking for the magnetostrictive properties of bright mild steel (C = 0.15). I'm especially interested in its elongation vs magnetic field strength curve. I've been looking everywhere and can't seem to find any data. Currently I'm busy with my engineering thesis on pulse-echo thermometry. I'm planning to send a pulse down a 2m steel rod (C1018) using a coil. The echoed pulse is picked up with a different coil. I hope someone can help. Cheers.
