以能形成氢化物的元素Ti、V为基的体心立方(bcc)合金，如今正作为贮氢材料而受到关注。但是这种bcc合金一般难以激活成可逆吸氢，bcc合金的吸附/解吸动力学通常较慢并有较大的迟滞性。除了加合金元素来解决这些问题外，最近发现控制显微组织也是一个很有潜力的方法。由于在Pd-H
A body-centered cubic (bcc) alloy based on the elements Ti and V that can form hydride is now attracting attention as a hydrogen storage material. However, this bcc alloy is generally difficult to activate into a reversible hydrogen absorption, and the adsorption / desorption kinetics of the bcc alloy is usually slow and has a large hysteresis. In addition to adding alloying elements to solve these problems, it has recently been discovered that controlling microstructures is also a promising method. Due to the Pd-H
