SUMMARY

The discussion focuses on the magnetostrictive properties of bright mild steel, specifically C1018 with a carbon content of 0.15. The user seeks data on the elongation versus magnetic field strength curve for this material, which is critical for their engineering thesis involving pulse-echo thermometry. The application involves sending a pulse through a 2m steel rod and capturing the echoed pulse with a coil. Historical context is provided regarding the use of thin magnetostrictive wires in high energy physics applications.

PREREQUISITES
  • Understanding of magnetostrictive materials and their properties
  • Familiarity with pulse-echo thermometry techniques
  • Knowledge of coil design and operation in electromagnetic applications
  • Basic principles of high energy physics and position resolution measurement
NEXT STEPS
  • Research the elongation vs magnetic field strength characteristics of C1018 steel
  • Explore advanced pulse-echo thermometry methods and applications
  • Investigate the design and implementation of magnetostrictive sensors
  • Study the historical applications of magnetostrictive materials in physics experiments
USEFUL FOR

Engineers, materials scientists, and researchers involved in magnetostrictive applications, particularly those working with steel and pulse-echo techniques in experimental physics.

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.

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
