    Abstract: 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.

    Abstract: A metal piece having at least two areas of lower mechanical strength than the body of the piece, said pieces being respectively arranged on one side and the other of a longitudinal central section (PM) of said piece and alternatively located in two locations separated longitudinally along the piece, the areas of lower mechanical strength than the body of the piece being formed by local control of the stamping temperature during a stamping process of the piece, notably a process comprising steps including heating the piece to a temperature range suitable for obtaining an austenitic stage, then stamping this piece in a stamping tool suitable for defining different temperatures in the different areas of the stamped piece, for example by virtue of the voids formed in the stamping tool or by local reheating of the stamping tool.

    Abstract translation: 一种金属片具有比所述片体更低的机械强度的至少两个区域，所述片分别布置在所述片的纵向中心部分（PM）的一侧和另一侧上，并且可选择地位于沿纵向方向分开的两个位置 该部件的机械强度低于通过在冲压加工过程中局部控制冲压温度而形成的机体的机械强度，特别是包括以下步骤的步骤：将该部件加热到适于获得奥氏体的温度范围 然后将该件冲压成适合于在冲压件的不同区域中定义不同温度的冲压工具，例如通过在冲压工具中形成的空隙或冲压工具的局部再加热。

    Abstract: Sheet metal workpieces are preheated to a temperature in the range of about 100° C. to about 500° C. for warm forming between press-actuated forming dies. The forming dies are not heated, but are coated with a liquid lubricating material suitable for the forming of the preheated sheet metal workpiece. For example, the liquid lubricating material is suitably a halogenated hydrocarbon that will adhere to unheated die surfaces and serve in the forming of the sheet metal workpiece into a vehicle body panel or other product. But the liquid lubricating material is composed so as to evaporate from surfaces of the formed workpiece at a temperature below about 200° C., so that the workpiece does not have to be cleaned before it is decoratively finished. The lubricant material may be vaporized, for example, into a warm stream of air or nitrogen and carried to a recovery or disposal system.
