Figure 8
P–T phase diagram of Pb. Solid lines represent phase boundaries reported in the literature. Their extrapolations to higher pressure are shown as dashed lines. The hatched area indicates the coexistence region of h.c.p. and b.c.c. phases as reported by Dewaele et al. (2007). The pressure of the transition from the h.c.p. to the b.c.c. phase at ambient temperature (Vanderborgh et al., 1990) has been recalibrated according to the pressure scale of Dewaele et al. (2004). |
