Nitinol, a group of NiTi alloys with compositions near equiatomic nickel and titanium, finds increasing applications in medical and actuator devices, etc. because of unique properties, such as shape memory effect, pseudo-elasticity and biocompatibility. However, joining (welding, brazing and soldering) of Nitinol is generally difficult, which in turn limits flexibility in the design and fabrication of Nitinol devices and hence impedes high volume commercialization of the alloys.

镍钛诺是一组成分接近等原子镍和钛的镍钛合金，由于具有形状记忆效应、伪弹性和生物相容性等独特性能，在医疗和执行器设备等领域得到越来越多的应用。然而，镍钛诺的连接（焊接、钎焊和钎焊）通常很困难，这反过来又限制了镍钛诺器件设计和制造的灵活性，从而阻碍了合金的大批量商业化。
