Abstract Scope |
Meteorites possess complex microstructures due to formation and structure evolution events spanning through astronomically long periods, along with extreme conditions in which they were formed. The resulting anisotropic structure makes precise structure-property studies challenging. Hence, a comprehensive understanding of how microstructural phase distribution and their respective mechanical properties connect to macro deformation behavior is crucial. In this study, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) was utilized to characterize meteorite Aba Panu (L3). In situ compression experiments were performed on machined cylindrical samples of meteorite. The crack development was studied via x-ray microtomography (XRT). Direct 3D correlation of in situ images of crack growth were used to form a comprehensive mechanistic understanding of crack development and deformation. Nanoindentation was used to complement the imaging study to obtain mechanical properties of individual constituent phases to round out this comprehensive multi-scale study. |
