Аннотация

The amorphous melt-spun (MS) Ti50Ni25Cu25 alloy is subjected to high-pressure torsion (HPT) at temperatures of 20-150 degrees C. The bright-field (BF) TEM images of the alloy change as a result of HPT processing, the view of the bright-field image depends on the temperature of HPT processing. HPT processing leads to a decrease in the energy of structural relaxation during heating up to 400 degrees C, in comparison with the initial MS ribbons. The temperature of crystallization of the MS Ti50Ni25Cu25 alloy decreases after HPT processing by 40-20 degrees C (depends on the temperature of HPT processing). In the MS Ti50Ni25Cu25 alloy, HPT processing and subsequent annealing produces noticeably finer grains than annealing at 450 degrees C of the initial MS alloy. Consequently, HPT processing alters the crystallization kinetics of the MS Ti50Ni25Cu25 alloy.
