new process for processing titanium nickel wire
A new technology for the processing of titanium nickel shape memory wire material has been successfully developed by the Institute of materials science, Tohoku University Japan.
This process includes the following steps:
1. The various metal layers are composed of different metal layers. And the thickness of each layer is determined by the chemical composition.
2. The rolled composite sheet is cut into fragments, and then the debris is filled into a container to form a blank.
3. The blank is extruded into a rod and then processed into filaments.
4. The filament was transformed into the desired Ti Ni intermetallic compound by thermal diffusion treatment.
With this process, the machinability of the composite can be improved, and the filaments with good microstructure can be obtained with high reduction ratio.
