Abstract

PURPOSE:To shorten the time required to heat treat an Fe-Co-Mn-C alloy by heat-treating the alloy while applying a specified extent or above of a magnetic field in the cold working direction. CONSTITUTION:A cold worked Fe-Co-Mn-C alloy contg. optionally one or more among Si, V, Mo, W, B, Cr, Be and Ti is heat-treated while applying >=500Oe magnetic field in the cold working direction. In case of <500Oe, the effect is remarkably recuded. The upper limit is set at about 5,000Oe.

Further, considering the practical aspects of the magnetic field application device, etc., the upper limit may be about 5.0000e. The purpose of the present invention can be sufficiently achieved by applying the magnetic field only while the alloy is maintained at a predetermined temperature. It may also include applying a magnetic field.
