Abstract: Nowadays, the production of metallic parts, namely sheet metal, with high strength and formability, represents a big challenge for automotive, aerospace and assembling industries. The present invention deals with a new plastic deformation process that allows, by controlling the strain path change, the production of sheet metals with a grain size of 1-2 micron and, consequently, with a yield stress 3-4 times than the ones obtained with conventional processes, keeping the same formability. The process is easy for industrialization and its optimization requires only two fundamental parameters that characterize the ratio of thickness reduction, shear strain and amplitude in the change of strain path.

Abstract: Applicants have discovered new composite materials and have developed a variety of new ways of making reactive composite materials (RCMs) and methods of controlling the properties and characteristics of the materials that are pertinent to numerous new or improved applications. This patent application is directed to new and improved ways of making reactive composite materials using mechanical deformation and making such materials with controlled, predictable characteristics.

Abstract: In an initial state of roller hemming processing, an erected flange 65 begins to be bent by a roller 48. At this time, a first plate 63 and a receiving face 15 are brought into tightly contact with each other at a contact point 70 between the roller 48 and the erected flange 65 by strongly pinching by the roller 48 and an auxiliary roller 51. On the other hand, in portions other than the contact point 70, the receiving face 15 tends to be separated from the first plate 63 by reaction. Since slider blocks 22 and 22 are movable along rails 21 and 21 on a side of the receiving die 10, the receiving die 10 rotates clockwise in the drawing about the contact point 70. A tight contact in the contact point 70 is guaranteed as the receiving die 10 rotates about the contact point 70. As a result, the hemming processing with a good shape can be achieved without wrinkling, ruffling, or deformation.

Abstract: An aluminum alloy sputter target having a sputter target face for sputtering the sputter target is disclosed. The sputter target face has a textured-metastable grain structure. The textured-metastable grain structure has a grain orientation ratio of at least 35 percent (200) orientation. The textured-metastable grain structure is stable during sputtering of the sputter target. The textured-metastable grain structure has a grain size of less than 5 ?m.

Then deforming the cooled aluminum alloy target blank introduces plastic strain into the target blank and reduces the grain size of the grains to form a textured-metastable grain structure. Finally, finishing the aluminum alloy target blank forms a finished sputter target that maintains the textured-metastable grain structure of the finished sputter target.
