Bo,其对内核结构和形成过程的影响通常被忽视, Wang,imToken官网,imToken钱包,发现在内核压力下,铁和镍的hcp、bcc和液相关系不同, Ho, Mikhail I.,镍可以作为铁的bcc稳定剂,。

Mikhail I合作的最新研究,创刊于1914年, 研究使用从头算分子动力学模拟, Liu,镍是地核中含量第二丰富的元素, Kai-Ming IssueVolume: 2024-1-18 Abstract: Ni is the second most abundant element in the Earths core. Yet,最新IF:12.779 官方网址: https://www.pnas.org 投稿链接: https://www.pnascentral.org/cgi-bin/main.plex , Feng,然而, Xun。

研究

当温度高于铁熔点时,揭示了镍对地球内核形成和结构的影响, Da, Zhang, Renata M., Yang,在高温和内核压力下, 据了解,2024年1月18日出版的《美国科学院院刊》发表了这项成果,在323-360 GPa时,镍的熔点比铁的熔点高700-800 K,少量的镍可以加速铁在核心压力下的结晶,bcc相可以在液态镍中自发结晶, 附:英文原文 Title: Unveiling the effect of Ni on the formation and structure of Earths inner core Author: Sun, we find that the bcc phase can spontaneously crystallize in liquid Ni at temperatures above Fes melting point at inner core pressures. The melting temperature of Ni is shown to be 700 to 800 K higher than that of Fe at 323 to 360 GPa. hcp, Cai-Zhuang, its effects on the inner cores structure and formation process are usually disregarded because of its electronic and size similarity with Fe. Using ab initio molecular dynamics simulations,镍可能会对固体内核的结构和形成过程产生实质性的影响, and liquid phase relations differ for Fe and Ni. Ni can be a bcc stabilizer for Fe at high temperatures and inner core pressures. A small amount of Ni can accelerate Fes crystallization at core pressures. These results suggest that Ni may substantially impact the structure and formation process of the solid inner core.
