摘要: Abstract The ability of ultrasonic vibrations (UVs) to influence the thermo-elastic phase transformation in TiNi alloys has been reported earlier. Particularly it was shown that preliminary ultrasound changes characteristic temperatures and kinetics. Also UVs allow realize a “sliding” shape memory effect (SME) when reverse occurs certain areas. In present paper is determine reversion storage deformation at temperature range direct TiNi. forming small thermal–mechanical hysteresis loops M s – f . Besides can initiate SME full measure. At same time austenite finish A reduced. On whole initiation with help caused by thermal as well power effects.
