Webbmethods and applications of Nitinol with a focus on stents, their most important current use. The Shape Memory Effect . The most common demonstration of the shape memory effect is that a piece of the alloy can be deformed – for example, by winding a piece of straight wire into a tight coil – and then the deformation can be completely WebbThe shape memory effect (SME) is what allows SMAs to return to their original shape after heating. The SME is a temperature-induced martensite-to-austenite phase transformation. That means that heat causes the alloy to change from martensite (B19) to austentite (B2).
