a [001]-oriented λ-Al0.12Ti2.88O5 micropillar 2 with a height-to-diameter ratio of 2:1. b, c Scanning electron microscopy images of micropillar 2 during and after loading, captured in the in-situ test. The compression tests were conducted using an Alemnis Standard Assembly platform that was equipped with a diamond flat punch indenter with a diameter of 10 μm. d The obtained stress-strain curve during the in-situ compression process; Stage I: Typical elastic deformation during the initial stage; Stage II: Plastic deformation occurred, resulting in a phase transition from the λ-phase to the β-phase; Stage III: The material reverted back to elastic deformation. The orange stars represent the phase transition pressure of micropillar 2. Source data are provided as a Source Data file. e Comparisons of this work with the reported results in terms of the phase transition temperature and pressure. f Schematic representation of the possible heat storage system with β/λ-AlxTi3-xO5 as the fundamental material for future lunar explorations.
