研究目的
To simulate local laser annealing of amorphous TiNiCu thin ribbon to create a layered nanostructured crystalline-amorphous functional material with the two-way shape memory effect for manufacturing nanoactuators.
研究成果
The simulation demonstrates the possibility of creating layered composite nanostructured materials with the two-way shape memory effect by laser treatment of TiNiCu amorphous ribbons. Optimal parameters for laser treatment were identified to achieve the desired crystalline-amorphous structure.
