Phase evolution process and hydrogen storage performances of V72Ti18Cr1o alloy prepared by Co-precipitation-reduction method
文献摘要：
The V72Ti18Cr10 alloy was prepared by a co-precipitation-reduction method in order to consume less energy during whole-life alloy manufacturing,and the phase evolution process in hydrogenation/dehydrogenation process was investigated.The structure refinement analysis of the alloy contented with 1 wt％hydrogen after hydrogenation shows that BCC phase,BCC-hydride phase and FCC phase coexisted,but little BCT phase was found.It indicates that the phase evolution process during hydrogenation was BCC→ BCC-hydride→ FCC,nevertheless the formation of BCT phase was restrained.The limited particle sizes of the alloy in the range of 0.1-5 μm and fewer defects than the normal alloy ingot contributed to the suppression of BCT formation.The annealed alloy,which had similar particle sizes with the unannealed alloy,has less unevenness of the compo-sitions than the unannealed alloy,and the annealed alloy showed flatter plateau in the hydrogenation PCT(pressure-composition-temperature)curves.However,the BCT phase in the annealed alloy appeared in its dehydrogenation process owing to the produced defects during the following dehydrogenation and the hydro-genation process.The alloy with the limited particle sizes even in the range from 0.1 μm to 5 μm could not prevent the generation of BCT phase in the dehydrogenation process.
