Abstract

Polymorphic transformation mechanism of η and η′ in single crystalline Cu₆Sn₅ has been investigated in this study. η phase exists at room temperature in the quenched specimens and transforms to η′ phase under aging at 150 °C for 40 d. The nucleation and growth of η′ phase is observed by field emission scanning electron microscope and surface reconstruction of polymorphic transformation is confirmed by both x-ray diffractometer and differential scanning calorimetry analysis. The results show that the volumetric strain energy is the dominant reason for occurring polymorphic transformation rather than order-disorder transition of η and η′ phases.
