Abstract: A metal-matrix composite of magnetostrictive powder is manufactured by dynamic compaction, such as that provided by the shock waves of an explosive, from a magnetostrictive powder in the presence of a matrix-forming metal. Under the conditions of dynamic compaction, property compromising phases between the powder and the binding metal are not formed, resulting in a composite essentially free of these phases. The composites may be formed by coating a magnetostrictive powder with a matrix-forming metal by a sputtering process and dynamically compacting the coated powder. A coated powder may also be made by sputtering a layered composite of metal-magnetostrictive material-metal, and grinding the layered composite. Metal-matrix composites may also be made by mixing the matrix-forming metal with a magnetostrictive powder and dynamically compressing the mixture. Metal-matrix composites of amorphous magnetostrictive powders may be annealed in the presence of a magnetic field.

Abstract: In one embodiment, composite constructions of the invention are in the form of a plurality of coated fibers bundled together to produce a fibrous composite construction in the form of a rod. Each fiber has a core formed from a hard phase material, that is surrounded by a shell formed from a binder phase material. In another embodiment of the invention, monolithic sheets of the hard phase material and the binder phase material are stacked and arranged to produce a swirled composite in the form of a rod. In still another embodiment of the invention, sheets formed from coated fibers are arranged to produce a swirled composite. Inserts for use in such drilling applications as roller cone rock bits and percussion hammer bits, and shear cutters for use in such drilling applications as drag bits, that are manufactured using conventional methods from these composite constructions exhibit increased fracture toughness due to the continuous binder phase around the hard phase of the composites.

Abstract: The present invention relates to decorative bows formed from a folded pattern of a laminated substrate. The substrate comprises one or more layers of printed material laminated between two layers of laminate film so that the print is visible on both sides of the substrate. In order to match the bow to gift wrap the substrate can be formed from gift wrap paper with a protective film laminated to the printed side of the paper. As gift wrap is normally only printed on one side, two sheets of gift wrap are laminated with their unprinted sides together resulting in a substrate having printed material on both sides with a protective film on each side. The gift wrap can be substituted with cardboard, fabric, vinyl, plastic or other film. By laminating the material the resulting bows are waterproof, durable, reusable.

In the sealing material made of expanded graphite of the present invention, a surface layer portion of an expanded graphite base material in which expanded graphite particles are pressurized is subjected to a blast process or the like, whereby the weight of the expanded graphite base material is reduced by a range of 0.5 to 3%, so that the diffraction peak of an X-ray diffraction of the exposed surface layer portion of the expanded graphite base material is in a range of 26.52.degree. to 26.48.degree.. In such a sealing material made of expanded graphite, the elongation rate and the tensile strength are improved, and also flexibility is remarkably improved. As a result, the product application range is extended and product productivity are improved.

Abstract: Shape-memory fibers are incorporated into a metal matrix material with a level of fiber-to-matrix bonding so that upon localized failure of matrix under load, the strains in fibers debond them from the matrix to the extent that fibers do not all rupture at the location of matrix failure. The pull-out process of fibers ruptured away from the matrix failure location provides the composite material with substantially increased ductility and energy absorption capacity after localized failure of the matrix. Pre-tensioning of shape-memory fibers impose sustained stresses on matrix which enhance the strength and energy absorption capacity of the composite material. The shape-memory fibers may be incorporated into a metal matrix at their end so that fibers pull out from the matrix under load and provide an energy-absorbing assembly.
