Elasticity or iron and iron-based alloys at conditions of the Earth`s and planetary cores

地核是地球上最遥远的区域，由于实验和计算方法的发展，以及观测技术的不断改进，地核一直是研究的重点。要想成功地解释地球物理数据，就需要了解铁基合金在地核物理条件下的弹性特性，即在压力超过150 GPa、温度高达6000 K的情况下。该项目的最终目标是设计、组装、调试和运行一个双面激光加热设备，该设备经过优化，可以在径向衍射几何结构中使用内部x射线设备在原位运行，然后用于研究地球和行星核心条件下铁、铁镍和铁镍硅合金的弹性。

The Earth’s core is the most remote region of our planet and is in focus of the highest research interest due to development of experimental and computational methods, as well as steady improvement in observational techniques. Successful interpretation of geophysical data requires information on the elastic properties of Fe-based alloys under physical conditions of the Earth's core, that is at pressures exceeding 150 GPa and temperatures up to 6000 K. The ultimate goal of the project is to design, assemble, commission and make operational a double-side laser heating facility optimized to operate in situ with in-house X-ray facilities in radial diffraction geometry, which will then be used to study elasticity of iron, iron-nickel, and iron-nickel-silicon alloys at condition of the Earth’s and planetary cores.
