High-temperature behavior of fine-grained polycrystalline bridgmanite during heating and cooling processes (FBRD04). The behavior during continuous heating (FBRD10) is shown for comparison. a Bridgmanite peak intensities as a function of temperature. The peak intensity was maintained during the cooling process. b Variation of relative unit cell volume (V/V0) as a function of temperature. The dashed line shows the thermal expansivity of bridgmanite. c Apparent pressure on bridgmanite grains. The amorphization-induced stress was maintained during the cooling process
