  • Preparation of hard magnetic alloys of a transition metal and lanthanide
    Patent number: 4533408
    Abstract: A method of preparing alloy of a transition metal and lanthanide comprising the steps of alloying a transition metal, boron, at least one lower-weight lanthanide having none or few stable compounds with iron, optionally one or more higher-weight lanthanides, a glass former, and optionally the pseudo lanthanide, yttrium; forming an amorphous or nearly amorphous metastable microstructure in the alloy; and heating the amorphous alloy to form a polycrystalline, multiphase, fine-grain single-domain structure.
    Type: Grant
    Filed: September 6, 1983
    Date of Patent: August 6, 1985
    Inventor: Norman C. Koon
  • Amorphous transition metal-lanthanide alloys
    Patent number: 4409043
    Abstract: An amorphous alloy of iron, boron, lanthanum, and a lanthanide wherein lanthanum and the lanthanide comprise up to 15 atomic percent of the alloy is obtained by rapidly quenching the molten alloy. The amorphous alloy is useful as a soft magnetic alloy.
    Type: Grant
    Filed: October 23, 1981
    Date of Patent: October 11, 1983
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventor: Norman C. Koon
  • Hard magnetic alloys of a transition metal and lanthanide
    Patent number: 4402770
    Abstract: A hard magnetic alloy comprises iron, boron, lanthanum, and a lanthanide is prepared by heating the corresponding amorphous alloy to a temperature from about 850 to 1200 K. in an inert atmosphere until a polycrystalline multiphase alloy with an average grain size not exceeding 400 A is formed.
    Type: Grant
    Filed: October 23, 1981
    Date of Patent: September 6, 1983
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventor: Norman C. Koon
  • Use of cubic rare earth-iron laves phase intermetallic compounds as magnetostrictive transducer materials
    Patent number: 4375372
    Abstract: A magnetostrictive device capable of large magnetostrictive strains is produced from RFe.sub.2 compounds wherein R is a rare earth element.
    Type: Grant
    Filed: March 16, 1972
    Date of Patent: March 1, 1983
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Norman C. Koon, Albert I. Schindler
  • Magnetostrictive devices
    Patent number: 4374665
    Abstract: A magnetostrictive device comprises a magnetostrictive component consisting essentially of an amorphous alloy of iron, boron, lanthanum and lanthanide.
