This work investigates the solid-states phase transformation behavior of Zr-Cr-Fe alloys during rapid cooling from β-phase region. SEM was used to characterize the microstructure evolution of Zr-Cr-Fe alloys containing different Mo and Bi contents. The results show that two different phase transformation modes involved during β to á transformation for different domains within prior â grains: (i) Martensitic transformation resulting in lath-shaped grains occurs within prior â grain interiors. (ii) Massive transformation generating massive-shaped grains initiated along two adjacent prior β parent grain boundaries. a lath width reduced with increasing Mo concentration while Mo strongly retards massive phase transformation. Interestingly microstructures exhibited no significant variation the case of specimens containing different Bi contents irrespective of the phase transformation modes.
