  • Metal part and process for its production
    Patent number: 5647831
    Abstract: A forming roll includes a base component having an angularly extending surface thereabout, a solder material applied to the surface and a wear ring on the solder and shaped to complement the angled surfaces of the base component. The Base component and the wear ring are made of materials with different thermal expansion coefficients so that when the parts are heated and then cooled a compressive strain results.
    Type: Grant
    Filed: November 8, 1994
    Date of Patent: July 15, 1997
    Inventor: Gunther Schroeder
  • Process to produce a reversible two-way shape memory effect in a component made from a material showing a one-way shape memory effect
    Patent number: 4411711
    Abstract: A noticeable two-way effect can be induced in a component consisting of a shape memory alloy exhibiting only a one-way effect by inhomogeneous deformation of the cross-section so that one part of the component cross-section is deformed sufficiently to hinder the free movement of the one-way effect in the lesser deformed part. Component in the form of a tension/compression (6/8), bending (3), or torsion rod.
