Avalanche dynamics of structural phase transitions in shape memory alloys by acoustic emission spectroscopy
In this work the avalanche dynamics of five shape memory samples has been analyzed by acoustic emission spectroscopy. The acoustic emission spectroscopy is particularly suitable for this analysis as it couples with high sensitivity to small structural changes caused by nucleation processes, …
