    摘要： A method of making an extruded strip less than 1.27 mms thick of lead antimony alloy containing 1 to 2% by weight antimony, the strip having an aspect ratio in excess of 10:1 comprises supplying the alloy at a temperature of 200.degree. C. to 280.degree. C. to an extrusion die and forcing it therethrough so that its temperature as it emerges from the die is in excess of 200.degree. C. and quenching the strip as it emerges from the die whereby its tensile strength within 6 hours of emerging from the die is about 35 Newtons/square mm.sup.2. This strip is suitable for conversion to a battery electrode.

    摘要： An asymmetric extrusion method, an extruded material extruded using the same, a die for asymmetric extrusion, and an asymmetric extrusion apparatus. According to the asymmetric extrusion method, an extruded material having a plate shape is formed by pushing an extruding material through a die including an extrusion hole having an asymmetric shape with respect to an extrusion direction of the extruding material, so as to extrude the extruding material while inducing shear strain in the extruding material.

    摘要： A method for fabricating a non-planar magnet includes extruding a precursor material including neodymium iron boron crystalline grains into an original anisotropic neodymium iron boron permanent magnet having an original shape, wherein the original anisotropic neodymium iron boron permanent magnet has at least about 90 percent neodymium iron boron magnetic material by volume. The original anisotropic neodymium iron boron permanent magnet is heated to a deformation temperature. The original anisotropic neodymium iron boron permanent magnet is deformed into a reshaped anisotropic neodymium iron boron permanent magnet having a second shape substantially different from the original shape using heated tooling to apply a deformation load to the original anisotropic neodymium iron boron permanent magnet. The original anisotropic neodymium iron boron permanent magnet and the reshaped anisotropic neodymium iron boron permanent magnet each have respective magnetic moments substantially aligned with a respective local surface normal corresponding to the respective magnetic moment.
