A
According to its physical properties, memory alloy wire can be divided into the following categories:
A
(1) One-way memory effect
The shape memory alloy deforms at a lower temperature, and after heating it can restore the shape before deformation. This shape memory phenomenon that exists only during heating is called the one-way memory effect.
(2) Two-way memory effect
Some alloys restore the shape of the high-temperature phase when heated, and can restore the shape of the low-temperature phase when cooled, which is called the double-pass memory effect.
(3) Global memory effect
The shape of the high-temperature phase is restored when heated, and it becomes the shape of the low-temperature phase with the same shape and the opposite orientation when cooled, which is called the global memory effect.
