Allotropes of iron - Wikipedia The primary phase of low-carbon or mild steel and most cast irons at room temperature is ferromagnetic α-Fe. It has a hardness of approximately 80 Brinell. The maximum solubility of carbon is about 0.02 wt% at 727 °C (1,341 °F) and 0.001% at 0 °C (32 °F). When it dissolves in iron, carbon atoms occupy interstitial "holes". Being about twice the diameter of the tetrahedral hole, the carbon ...

PDF Iron-Nickel alloy in the Earth's core [8] Compared to the phase diagram of pure Fe [Hemley and Mao, 2001], it is evident that the stability field of the fcc phase can be extended to higher pressures and lower temperatures with the addition of Ni (Figure 1). However, the effect of Ni on the phase diagram of Fe is not as dramatic as the addition of silicon in Fe [Lin et al., 2002].
