为了在组织水平上理解骨的特征，需要研究纳米尺度下骨的结构、组织和力学性能以及它们之间的相互作用。这些信息将有助于了解骨骼特性的变化，包括刚度、强度和韧性，并为评估老化和患病骨骼以及开发下一代仿生材料提供方法。近年来，x射线衍射技术作为研究骨纳米结构的有用的非破坏性工具获得了越来越多的兴趣。本文综述了近年来该领域的研究进展，并简要介绍了相关的实验方法。本文从原位应变、残余应力应变和晶体取向等方面综述了x射线衍射技术在骨矿物晶体结构和力学性能研究中的应用。
Abstract To understand the characteristics of bone at the tissue level, the structure, organization and mechanical properties of the underlying levels down to the nanoscale as well as their mutual interactions need to be investigated. Such information would help understand changes in the bone properties including stiffness, strength and toughness and provide ways to assess the aged and diseased bones and the development of next generation of bio-inspired materials. X-ray diffraction techniques have gained increased interest in recent years as useful non-destructive tools for investigating the nanostructure of bone. This review provides an overview on the recent progress in this field and briefly introduces the related experimental approach. The application of x-ray diffraction to elucidating the structural and mechanical properties of mineral crystals in bone is reviewed in terms of characterization of in situ strain, residual stress–strain and crystal orientation.
