Abstract

Meteorites provide access to information on the formation and evolution of planetary bodies which is otherwise difficult to study. The unique nature of these samples and their relative scarcity means that non-destructive analysis techniques are needed to study their properties.

This paper uses the laser ultrasound technique spatially resolved acoustic spectroscopy to non-destructively determine both the crystal orientation and the single crystal elastic constants (

C_{i j}

) of a sample of the Gibeon meteorite. There are no published values to directly compare the results of this study, as non-destructive measurements of the single crystal elasticity on granular material have not been possible. Therefore, comparisons with theoretical values for man-made iron-nickel alloys are given showing the

C_{i j}

values are in the expected range. There are studies providing bulk elastic properties of meteorites, and so calculated bulk properties derived from the single crystal elasticity measurements are compared and also agree well.

陨石提供了有关行星体形成和演变的信息，而这些信息是很难研究的。本文利用激光超声技术空间分辨声学光谱法，非破坏性地测定了吉比翁陨石样本的晶体取向和单晶体弹性常数（Cij）。由于无法对颗粒材料的单晶体弹性进行非破坏性测量，因此没有公开发表的数值可直接与本研究的结果进行比较。因此，与人造铁镍合金的理论值比较显示 Cij 值在预期范围内。有研究提供了陨石的块体弹性特性，因此对根据单晶弹性测量得出的计算块体特性进行了比较，结果也非常吻合。

期刊介绍： Scripta Materialia is a LETTERS journal of Acta Materialia, providing a forum for the rapid publication of short communications on the relationship between the structure and the properties of inorganic materials. The emphasis is on originality rather than incremental research. Short reports on the development of materials with novel or substantially improved properties are also welcomed. Emphasis is on either the functional or mechanical behavior of metals, ceramics and semiconductors at all length scales.
