Magnetostrictive properties of steel

  1. Jul 13, 2009 #1

    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.

    We used to use thin magnetostrictive wires (< 1/16" dia) to read out high energy physics spark chambers with roughly 1 mm position resolution using the time delay of the magnetostriction pulse. See
