MATERIAL WITH A MEMORY EFFECT OF THE FORM Russian patent published in 2005 - IPC

FIELD: medicine; instrument-making industry; radio industry; production of materials with a memory effect of the form.

SUBSTANCE: the invention is pertaining to the materials with a memory effect of the form and with the modified surface, which may be used as implants in medicine and as the temperature sensors, thermo-sensitive and executive elements and designs in instrument-making industry, the radio industry. The offered material consists of a base made out of a titanium nickelide of the following composition (in at. %): titanium - 49-51, nickel - the rest, and the surface layer modified by alloying elements. The modified surface layer is formed by irradiation with a low-energy high-current electronic beam and has a depth of 1000-2500 nanometers and the dimensions of the crystal grains of no more than 30 nanometers. In the capacity of the alloying elements it contains oxygen and carbon at the following ratio of components (in at. %): oxygen - 10-20, carbon - 10-15, titanium - 40-50, nickel - the rest. The technical result of the invention is production of the materials with an effect of memory of the form and a high degree capability of the form restoration both at a low and high deforming loadings.

EFFECT: the invention ensures production of the materials with an effect of memory of the form and a high degree capability of the form restoration both at a low and high deforming loadings.
