摘要：

Magnetic properties of Fe-Mn-Al alloys containing 1.0 mass% Al and 0. 5-2.0 mass% Mn have been evaluated. The hot rolled alloys after annealing at 750-800-degrees-C have shown high induction, high remanence, low coercive force and reasonably high permeability. The annealed alloys have exhibited high tensile strength (335-345 MPa) and high elongation (30-40%). The d.c. electrical resistivity of the alloys have been found to be in the range 20-22 x 10(-8) OMEGA.m Microstructural studies of the alloys have also been made and correlated with the magnetic properties.
