  • Method for the thermomechanical treatment of a titanium alloy, and resulting alloy and prosthesis
    Patent number: 9464344
    Abstract: According to a thermomechanical treatment process for a titanium alloy including between 23 and 27% niobium in atomic proportion, between 0 and 10% zirconium, and between 0 and 1% oxygen, nitrogen and/or silicon, the following steps are performed: a) an increase of a sample of the alloy to a temperature higher than 900° C., b) a fast quench, c) a severe cold strain, d) an ageing treatment at a temperature included between 200 and 600° C., the time of the ageing treatment being included between 10 seconds and 10 minutes. Alloy obtained by this process and prostheses made from such an alloy.

  • Eyeglass frame with very high recoverable deformability
    Patent number: 5640217
    Abstract: An eyeglass frame wherein one of the components such as the temples, the bridge and/or the connection bar between the eyewires is made of a shaped memory alloy which is able to regain its initial shape by simple heating after having undergone a permanent deformation and a lower temperature.

  • Apparatus for the translatory manipulation of an element such as an axle
    Patent number: 4879467
    Abstract: The present invention relates to an apparatus for translatory manipulation of an element, such as an axle.Apparatus characterized in that it comprises a displacement device (2) for each direction in space in which the axle (1) is to be manipulated, each displacement device (2) comprising two blades (3) prestressed in opposition, constituted by an alloy which is pseudoelastic or has shape memory, disposed on opposite sides of heating and/or cooling means (4) giving rise to a thermal gradient between the two blades (3) and thus their martensitic transformation causing their deformation.
