Abstract
A reversibly necked material capable of stretching at least about 75 percent and recovering at least about 50 percent when stretched about 75 percent, typically in a direction generally parallel to the direction of necking. The reversibly necked material is made by applying a tensioning force to at least one material to neck the material, heating the necked material, and cooling the necked material that the reversibly necked material possesses a greater heat of fusion and/or a lower onset of melting than the material before heating while stretched.
