    • To provide for an inexpensive magnet alloy, isotropic and nearly isotropic permanent magnet properties are developed in Fe-Mo-Ni alloys. Manufacture may be by a method which comprises steps of annealing, optional deforming by a limited amount, and aging.Typical magnetic properties of alloys of the invention are a coercive force in the range of 50-500 oersted, a magnetic remanence in the range of 7000-14000 gauss, and a magnetic squareness ratio of less than 0.9. Alloys of the invention are highly ductile even after plastic deformation, they are readily bonded to aluminum supports (as used, e.g., in the manufacture of twistor memories), and they are readily etched by etchants which leave aluminum unaffected.
    • 为了提供廉价的磁体合金,在Fe-Mo-Ni合金中开发出各向同性和几乎各向同性的永磁体性能。 制造可以通过包括退火步骤,任选的有限量的变形和老化的方法。 本发明的合金的典型的磁性是50-500奥斯特的矫顽力,7000-14000高斯范围内的磁剩磁,小于0.9的磁矩比。 本发明的合金即使在塑性变形之后也具有高延展性,它们易于粘合到铝支架上(例如用于制造二极管存储器),并且它们容易地被不会影响铝的蚀刻剂蚀刻。

    • Magnetically actuated devices such as, e.g., switches and synchronizers typically comprise a magnetically semihard component having a square B-H hysteresis loop and high remanent induction. Among alloys having such properties are Co-Fe-V, Co-Fe-Nb, and Co-Fe-Ni-Al-Ti alloys which, however, contain undesirably large amounts of cobalt.According to the invention, devices are equipped with a magnetically semihard, high-remanence Fe-Mo-Ni alloy which comprises Mo in a preferred amount in the range of 2-26 weight percent and Ni in a preferred amount in the range of 0.5-15 weight percent.Magnets made from alloys of the invention may be shaped, e.g., by cold drawing, rolling, bending, or flattening and may be used in devices such as, e.g., electrical contact switches, hysteresis motors, and other magnetically actuated devices.Preparation of alloys of the invention may be by a treatment of annealing and aging or deformation and aging.
