研究了Zr0.9Ti0.1V2合金的循环吸放氢性能。合金在吸氢P-C-T曲线的特征区域内具有良好的循环吸氢稳定性,在P-C-T曲线的吸氢平台区(H/A为0.5左右)、吸氢形成氢化物初始阶段(H/A为1~1.2)、吸氢形成氢化物中间阶段(H/A为1.4左右)吸放氢循环测试中,每组循环内合金的吸氢量差别非常小,循环吸氢稳定性很好。经过70次吸氢循环后,合金的吸氢量可以恢复到1.957(H/A),合金的粉碎程度很低,表明合金具有良好的循环吸氢能力。
The cyclic hydrogen absorption and desorption performance of Zr0.9Ti0.1V2 alloy was studied. The alloy has good cyclic hydrogen absorption stability in the characteristic region of the hydrogen absorption PCT curve. In the hydrogen absorption platform region of the PCT curve (H / A is about 0.5), the initial stage of hydride formation by hydrogen absorption (H / A is 1 ~ 1.2), hydrogen absorption hydrogen formation intermediate stage (H / A is about 1.4) absorption and discharge hydrogen cycle test, each cycle of the alloy hydrogen absorption is very small difference between the hydrogen cycle stability is very good. After 70 cycles of hydrogen absorption, the amount of hydrogen absorbed by the alloy can be recovered to 1.957 (H / A) and the degree of comminution of the alloy is very low, indicating that the alloy has good cyclic hydrogen absorption capacity.
