  • Patent number: 8685183
    Abstract: Metal ingots for forming single-crystal shape-memory alloys (SMAs) may be fabricated with high reliability and control by alloying thin layers of material together. In this method, a reactive layer (e.g., aluminum) is provided in thin flat layers between layers of other materials (e.g., copper and layers of nickel). When the stacked layers are vacuum heated in a crucible to the melting temperature of the reactive layer, it becomes reactive and chemically bonds to the other layers, and may form eutectics that, as the temperature is further increased, melt homogeneously and congruently at temperatures below the melting temperatures of copper and nickel. Oxidation and evaporation are greatly reduced compared to other methods of alloying, and loss of material from turbulence is minimized.

  • Publication number: 20100297463
    Abstract: A strip-shaped or plate-shaped composite metal object and a method for the production thereof. The composite metal object has at least two layers of the same metal. The layers have been brought by a heat pretreatment to a temperature such that a mutual diffusion bond has resulted through subsequent pressing of the layers against one another, while reducing the thickness by 5 to 25% and preferably 8 to 15%. A layer, which on the side thereof facing an adjacent layer has strip-shaped recesses, which are closed by the adjacent layer to form channels when the layers are pressed together, is used as one of the layers. The channels in the composite metal object allow the inclusion of additional elements before processed further to form an implement. The channels remain extensively preserved during the production and further processing of the composite model object.
