摘要： Certain polymer materials, including perfluorosulfonic acid ionomers, have been found to be capable of being deformed from an initial permanent shape into three or more temporary shapes. An article thus formed from such a polymer material may be used initially in a final temporary shape. As the article is progressively heated, the polymer composition reverts successively from its final temporary shape through its intermediate temporary shapes. If a suitable temperature is reached, the original permanent shape is recovered. The article may be devised to serve successive functions in each of its several shapes.
摘要翻译：已经发现某些聚合物材料，包括全氟磺酸离聚物，能够从初始永久形状变形成三种或更多种临时形状。这样由这种聚合物材料形成的制品可以最初以最终的临时形状使用。随着制品逐渐加热，聚合物组合物通过其中间临时形状从其最终的临时形状连续地回复。如果达到合适的温度，则恢复原始的永久形状。可以设计该物品以在其几种形状中的每一种中提供连续的功能。

摘要： In substantial volume production operations involving hot blow forming or hot stamping of aluminum alloy sheet workpieces, debris largely comprised of particles of aluminum alloy material adheres to critical forming surfaces of the heated steel tools. This debris mars forming surfaces and causes defects in aluminum alloy parts formed against them. Such aluminum-rich debris may be reactively transformed to change its adherent properties and removed from tool surfaces without removing the heated tool from production. In one embodiment, a hot sacrificial magnesium sheet may be formed on the tool(s) to alloy with aluminum debris and carry it from the forming surface.

摘要： The elevated temperature forming of magnesium based alloy workpieces by stretching, drawing, bending (or the like) a surface of the heated workpiece over the forming surface of a forming tool is improved by forming an integral adherent layer of magnesium hydroxide on the tool-contacted surface(s) of the magnesium alloy workpiece. The magnesium hydroxide layer may be formed by treating the surface(s) of the sheet with an aqueous salt solution (e.g., sodium chloride) at a temperature and for a time to form a protective layer of desired thickness (e.g., up to about thirty micrometers). If desired, an additional layer of forming lubricant, such as a film comprising boron nitride, may be applied to the magnesium hydroxide layer.

摘要： Work hardenable aluminum alloy sheet material is progressively stamped to a final stamped shape in a succession of stamping operations. A blank sheet of annealed starting material is stamped into a least a first preform shape between heated stamping tools to form a preform shape and subsequently anneal the worked preform shape. After one or more annealed preform shapes have been progressively attained, the last preform shape is cooled, if necessary, and stamped to its final stamped shape between unheated stamping tools.

摘要： A tailor welded blank for use in a fluid-forming operation includes a first sheet element having a physical characteristic with a first value and a second sheet element having the physical characteristic with a second value different from the first value. The first and second sheet elements are welded together at at least one weld region to form at least a portion of a tailor welded blank. When the tailor welded blank is processed in a fluid forming process, the first and second values of the physical characteristic result in said first and second sheet elements having approximately equal effective strength values such that said first and second sheet elements deform at an approximately equal rate during the fluid forming process and local thinning and failure initiation is reduced at the at least one weld region and throughout the first and second sheet elements.
