The nucleation behavior of liquid iron with various iron oxides was investigated through an in situ synchrotron radiation analysis and undercooling measurements. When Al and Si were added into the liquid in an oxygen atmosphere, three typical nucleation behaviors with three different undercooling values were observed during a thermocycling treatment. Further investigation showed that the nucleation undercooling (ΔT) increased linearly with variations in the nearest neighbor distance (r₁) values of the liquid.

液态铁的成核过冷与其液体结构之间的定量关系：通过原位同步辐射研究

通过原位同步加速器辐射分析和过冷测量研究了液态铁与各种氧化铁的成核行为。当在氧气气氛中将Al和Si添加到液体中时，在热循环处理过程中观察到三种典型的成核行为，具有三种不同的过冷值。进一步的研究表明，成核过冷度（ΔT）随着液体最近邻距离（r ₁）值的变化而线性增加。
