Hydrogenation-induced microstructure changes of pseudo-binary (PrxMg1−x)Ni2 Laves compounds

- We systematically investigate hydrogenation-induced microstructural changes of pseudo-binary (PrxMg1−x)Ni2 Laves compounds.
- We use transmission electron microscopy (TEM), instead of X-ray diffraction techniques conventinally used so far.
- We find a novel hydrogenation-induced phenomenon, which is hydrogenation-induced micro-phase separation (HIMPS).
