Magnetic alloy on the base of a nickel–titanium system with the shape memory Patent on invention No.87799. B.Ye.Paton, D.M. Kaleko, Yu. M. Koval, L.M.Neganov, A.P.Shpak. It is registered in State Patent Registration Book of Ukraine on inventions on 10.08.2009, Bul. No.15, 2009. |
Examples of practical usage of the technologies developed at the department
The gradient material and products made of it (cores, the spring) having the shape memory in a wide
Thermosensitive elements made of alloy with the shape memory for the tumblers
Temperature compensator for power lines. The spring is made of the alloy with the shape memory Due to the unique technological parameters of the alloy for medical purposes, developed at the department, it is possible to obtain the cast miniature components with the irregular shape, which have the shape memory effect without additional heat treatment
New composite material Cu–Al–Ni/ invar with the controlled coefficient of thermal expansion and high electric conductivity |
