Study of the Acoustic Emission and Calorimetric Properties of Titanium Nickelide after Barocryodeformation

The influence of barocryodeformation at –196°C on the phase transitions and the acoustic emission in titanium nickelide is studied. Barocryodeformation changes the temperature ranges and causes a two-stage character of the reverse martensite transformation with a decrease in the total heat absorption. The total number of acoustic emission signals increases and their energy decreases for the reverse phase transformation during heating of the samples subjected to barocryodeformation.
