Abstract

Electron-irradiation induced amorphization of NiTi alloys has been investigated in a temperature range from 50 to 393 K by high voltage electron microscopy with the following results: A crystalline-amorphous transition occurs when the total dose of electrons reaches a certain value. The critical value decreases with decreasing irradiation temperature and becomes almost constant with about 2×10 25 e/m 2 below 100 K. Process of the transition is also revealed.
