Effect of Laser Treatment on Shape Memory Properties of TiNiCu Alloy

The work deals with the research of the effect of pulsed laser radiation (λ=248 nm) on the structure and the manifestation of the shape memory effects (SMEs) in the Ti50Ni25Cu25 alloy, produced by melt spinning technique. It has been revealed that the proposed method of laser treatment leads to the formation of structural amorphous-crystalline composite demonstrating the pronounced two-way SME. A dependence of the two-way SME on the number of laser radiation pulses was determined.
