Phase relations of Fe‐Si alloy up to core conditions: Implications for the Earth inner core

X‐ray diffraction experiments were conducted to 257 GPa and high temperature in situ on an iron‐silicon alloy containing 3.4 wt% silicon, a candidate for the Earth's inner core forming material. The results revealed that fcc and hcp phases coexist up to 104 GPa. A single hcp phase is stable at...
