Peculiarities of the martensitic transformation in ZrCu intermetallic compound - potential high temperature SMA

Abstract

Interaction of two martensitic phases during martensitic transformation (MT) in ZrCu intermetallic compound was studied by means of in situ high-temperature X-ray diffraction studies, internal friction and calorimetric measurements. Some regularities of the mutual formation and disappearance of two martensites on thermal cycling through the temperature interval of the MT were established. The mechanism of the MT in ZrCu intermetallic compounds is discussed.
