  • Patent number: 8591669
    Abstract: The present disclosure is directed to a method of shaping a starting material of polycrystalline Fe—Ga alloy sheet of varying texture or crystal orientation. The method includes texturing the surface of the Fe—Ga alloy sheet to re-orient polycrystalline Fe—Ga crystals of the polycrystalline Fe—Ga alloy sheet to increase the uniformity of the crystal orientation of the Fe—Ga alloy sheet. The texturing step includes: initially deforming the Fe—Ga alloy sheet by hot rolling; subsequently deforming the previously hot rolled Fe—Ga alloy sheet by warm rolling; and annealing the previously warm rolled Fe—Ga alloy sheet. The method provides an alloy having a saturation magnetostriction potential greater than 60 ppm in applied fields of between 200-600 Oersted. During the annealing step H2S gas is added to introduce sulfur for promoting surface-energy-induced selective growth of {110} grain. The annealing step is performed in an atmosphere of argon gas.

  • Publication number: 20130291657
    Abstract: A sensor system for analysis of forces and motions on a rotating shaft using non-contact magneto-elastic sensors with the ability to measure any one or more of the following parameters of the shaft: (1) torque, (2) rate of change of torque, (3) shaft speed, (4) shaft position, (5) bending moments in the shaft in 2 directions, (6) axial force, (7) shaft power and/or system efficiency. The sensor system generally includes a magneto-elastic sensor patches fixedly applied to the rotating shaft, and a magnetic field pick up surrounding both said shaft and said magneto-elastic material but not in contact therewith, said magnetic field pick up comprising a clam-shell toroidal collar incorporating a combination of a magnetic field sensors.
