| 摘 要： | 用Ti部分取代V对ZrV2合金进行合金化改性,研究铸态Zr-Ti-V合金的表面形貌,初始活化和吸氢动力学性能.发现,Zr-Ti-V合金具有较低的活化温度;由柱状晶和细小等轴晶组成的复合结构使其可以快速吸氢并具有良好的抗粉化能力.吸氢动力学曲线表现双斜率特征,573～673 K之间存在一个临界温度Tc,在Tc以下,吸氢速率由大变小,受相变速率控制;Tc以上,吸氢速率由小变大,由表面过程控制.

| Abstract: | In order to improve the properties and to prepare Zr-Ti-V alloy,V was partially substituted with Ti in ZrV2 alloy. The microstructure,the initial activation and dynamic performances of hydrogen absorption of the alloy are studied. It was found that the Zr-Ti-V alloy has a low activation temperature to absorb hydrogen fast and a good anti-powder capability due to the composite structure consisting of columnar crystals and small equiaxed crystals. The kinetic curves of hydrogen absorption exhibit dual-slope c... |
