What is the change of nickel-titanium paper clip after encountering 65℃ hot water?

Nickel-titanium paper clips will have shape recovery after encountering hot water at 65 ° C, which is determined by the shape memory effect of nickel-titanium alloy.

Process:

1. Shape memory effect: Nitinol alloy is processed into a specific shape at high temperature (austenitic phase), and can be deformed after cooling (martensitic phase). When the temperature rises again above the phase transition temperature, the alloy will revert to the previously preset shape.

2. 65 ° C hot water: 65 ° C temperature is higher than the phase transition temperature of most nickelinol alloys (usually between 40 ° C and 60 ° C), so the paper clip will be transformed from martensitic phase to austenite phase and return to its original shape.

For example:

If the nickel-titanium paper clip is bent into other shapes and then placed in hot water at 65 ° C, the paper clip will gradually return to its original shape.

Note:

Different components of nickel-titanium alloys have different phase change temperatures, so not all nickel-titanium paper clips can recover their shape in hot water at 65 ° C.

The speed and extent of shape recovery depends on factors such as the temperature of the hot water, the size and shape of the paper clip.

In SUMMARY:

Nickel-titanium paper clips regain their shape in hot water at 65 ° C, due to their unique shape memory effect.

This feature makes it have broad application prospects in medical, aerospace and other fields.
