... of Si under conditions in planetary and satellite cores is less than ∼1.2 km. Additionally, the estimated strain of plastic deformation in the Earth's inner core, caused by the Harper–Dorn creep, reaches more than 10 3 at a stress level of 10 3 –10 4 Pa, although the inner core might be slightly...

... growth rate of -iron, the dominant phase in the Earth s inner core, is high enough for appreciable grain growth to occur. This result indicates that grain size and stress-insensitive rheology (Harper Dorn creep) is likely to be the dominant deformation mechanism in the inner core and that a uniform...
