Description

<jats:title>ABSTRACT</jats:title><jats:p>Magnetic properties in ferromagnetic materials are very sensitive to lattice defects such as dislocations and planar faults. Dislocation substructures and planar faults in fatigued intermetallic compounds of Ni<jats:sub>3</jats:sub>Fe, Fe<jats:sub>3</jats:sub>Al and FeAl were observed using change in magnetic properties of spontaneous magnetization and high-field susceptibility. This magnetic technique was applied for the nondestructive evaluation of fatigue life.</jats:p>
