From a technological point of view Nitinol is very difficult to join with dissimilar materials, especially stainless steel. At welding of Nitinol brittle intermetallic compounds (for example Ti₂Ni₃) are formed which considerably reduce joint strength.

In respect to technology of materials explosive welding is promising method for joining TiNi when influence of high temperatures is not enough and intermetallic phase at the interface practically does not present.

The use of high-speed strain allowed TiNi-steel joint, TiNi-TiNi to receive providing high thermoelastic and reflexive characteristics of the load-bearing elements operating on shape memory effect. At the expense of heat treatment selection it was possible to recover thermoelastic properties of TiNi alloys subjected to high-speed strain by explosive welding.
