The microstructure of strained β-PbF2 crystals is investigated by optical and scanning electron microscopy. It is established that the α-PbF2 previously observed by x-ray diffraction methods during the straining of cubic PbF2 nucleates predominantly on structural defects like slip lines and bands. The kinetics of the growth of α-PbF2 particles during the straining of β-PbF2 crystals and during a postdeformation anneal is investigated. The results of the experiments point to the involvement of diffusion in the growth of α-PbF2.
