stress-temperature graph of martensite and austenite lines in a shape memory alloy, illustrating the difference between the shape memory effect and pseudoelasticity
Summary
[edit]
| Description |
English: The shape memory effect happens when detwinned martensite is heated into austenite (moving right on the graph). This phase transformation creates austenite with the same macroscopic shape as the twinned martensite. When the austenite is cooled back into martensite, the shape does not change.
The pseudoelastic effect happens when austenite is stressed into martensite (moving up on the graph). This phase transformation allows the martensite to detwin. When the load is released, the detwinned martensite transforms back into austenite with the original shape, creating the illusion of superelasticity. |
