Nanoindentation, high-angular resolution electron backscatter diffraction (HR-EBSD), and transmission electron microscopy data in synthetic forsterite bicrystal samples (NERC Grant NE/S00162X/1)

The data are nanoindentation, high-angular resolution electron backscatter diffraction (HR-EBSD), and transmission electron microscopy data collected on samples of synthetic forsterite bicrystals at room temperature. The data were collected in two samples, with high- and low- angle grain boundaries (HAGB, 60°, [100]/(011) and SB, 13°, [100]/(016)). The EBSD data are the basis for the HR-EBSD calculation. The HR-EBSD results are presented as Matlab data files. The nanoindentation data are categorised as a function of sample (‘ol13’ – low-angle grain boundary; and ‘ol60’ – high-angle grain boundary), and indenter tip geometry (spherical (with a 10 or 5 micron radius) and pyramidal (Berkovich). The data are presented in .xls files. The TEM data are presented as .tif files. The TEM data were collected in specific indents with various distances from the interfaces. These data have been published in the manuscript: : The Role of Grain Boundaries in Low-Temperature Plasticity of Olivine Revealed by Nanoindentation, with the DOI: 10.1029/2023JB026763

本数据集包含室温下对合成方解石二晶样品进行的纳米压痕、高角分辨率电子背散射衍射（HR-EBSD）和透射电子显微镜（TEM）数据。数据收集自两个样品，分别具有高角度和低角度晶界（HAGB，60°，[100]/(011) 和 SB，13°，[100]/(016)）。EBSD数据是HR-EBSD计算的基础。HR-EBSD结果以Matlab数据文件形式呈现。纳米压痕数据根据样品（‘ol13’——低角度晶界；和‘ol60’——高角度晶界）以及压痕尖端几何形状（球形（半径为10或5微米）和金字塔形（Berkovich））进行分类。数据以.xls文件格式呈现。TEM数据以.tif文件格式呈现。TEM数据是在特定压痕处，从界面不同距离收集的。这些数据已在以下论文中发表：《纳米压痕揭示橄榄石低温塑性的晶界作用》，DOI：10.1029/2023JB026763。
