چکیده انگلیسی
Laser micro-welding has been considered one of the most promising joining methods of manufacturing Nitinol biomedical devices. However, there is still a lack of understanding about how laser micro-welding influences the microstructure. This work attempts to reveal the phase content within various microstructural zones of laser micro-welded crossed Nitinol wires by transmission electron microscopy (TEM) with the assistance of the focused ion beam (FIB) technique. The base metal is composed of a single austenite phase (B2). The fusion zone exhibits the coexistence of austenite matrix and several intermetallics (T2Ni, TiNi3 and Ti3Ni4). The precipitation of R-phase was observed in HAZ with B2 matrix due to thermally induced stresses during welding.
