Synthetic Forsterite Bicrystal Nanoindentation and Microscopy Data

NERC Grant NE/S00162X/1 data includes nanoindentation, high-angular resolution electron backscatter diffraction (HR-EBSD), and transmission electron microscopy data from synthetic forsterite bicrystals. The data were collected on two samples with high- and low-angle grain boundaries at room temperature. These data support the published manuscript 'The Role of Grain Boundaries in Low-Temperature Plasticity of Olivine Revealed by Nanoindentation' (DOI: 10.1029/2023JB026763).

Use Cases

• Modeling low-temperature plasticity in olivine based on nanoindentation data categorized by grain boundary type and indenter geometry.
• Analyzing stress and strain fields near grain boundaries based on HR-EBSD calculation results.
• Investigating dislocation structures and deformation mechanisms using transmission electron microscopy images from specific indents.

Strengths

• Data includes results from three complementary experimental techniques: nanoindentation, HR-EBSD, and TEM.
• Samples are well-defined synthetic bicrystals with specific high-angle (60°) and low-angle (13°) grain boundaries.
• Data is directly linked to a peer-reviewed publication (DOI: 10.1029/2023JB026763).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect experimental bias inherent to the specific synthetic samples and laboratory conditions.
