Abstract

ABSTRACT Anelastic measurement by cyclic loading under high pressure has been developed by means of in situ X-ray observation at a synchrotron facility. In this method, the reference material is a key factor to precisely determine attenuation and moduli of unknown materials. We compared the performance of three types of reference materials (dense polycrystalline alumina, alumina single-crystal parallel to c-axis, and flexible graphite) under the pressure of 3 GPa and the temperature range between 1173 and 1373 K. The phase lags of strain between reference materials and samples show that the flexible graphite is less attenuated than dense polycrystalline alumina and alumina single crystal in various periods. The strain ratios show that the flexible graphite is much softer and can produce the measurable strain in the limited displacement. The flexible graphite, as reference material, is more excellent to detect the relatively lower energy dispersion of mantle minerals at high pressure.

探索高压下循环载荷非弹性测量的最佳参考材料

摘要在同步加速器装置上，通过原位X射线观测，发展了高压下循环加载的非弹性测量方法。在这种方法中，参考材料是精确确定未知材料衰减和模量的关键因素。我们比较了三种类型的参考材料（致密多晶氧化铝、平行于c轴的氧化铝单晶和柔性石墨）在3 GPa和1173到1373之间的温度范围 K.参考材料和样品之间的应变相位滞后表明，在不同时期，柔性石墨的衰减小于致密多晶氧化铝和氧化铝单晶。应变比表明，柔性石墨比柔性石墨软得多，能够在有限位移中产生可测量的应变。柔性石墨作为参考材料，在高压下检测地幔矿物相对较低的能量色散方面更为出色。
