Abstract:
1. A method of shaping a starting material of polycrystalline Fe—Ga alloy sheet of varying texture or crystal orientation, said method comprising: 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 to have a {110}<001>orientation according to the standard notation of Miller's indices, wherein 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 during a time period greater than one hour and at a temperature greater than or equal to 1000° C., wherein the method provides an alloy having a saturation magnetostriction potential greater than 60 ppm in applied fields of between 200-600 Oersted, wherein during the annealing step H
