Abstract :
The thermodynamic correlation between magnetostrictive and magnetomechanical effects is tested using reversible measurements of the uniaxial isostress magnetostrictive and isofield magnetomechanical coefficients. All measurements are on samples of the same 2% Mn pipeline steel, using both tensile and compressive stresses. The agreement is claimed to be satisfactory considering the high sensitivity required for the measurements
