The effects of addition of Zr, Ni and Zr7Ni10 on the crystal structure, microstructure and hydrogen absorption of Body Centred Cubic (BCC) 52Ti-12V-36Cr were investigated. We found that addition of Zr and/or Ni led to the formation of a Ni/Zr rich secondary phase. This secondary phase is responsible for the much faster first hydrogenation of the alloys with additives compared to the bare BCC alloy. Zirconium addition had positive influence on incubation time and intrinsic hydrogenation kinetics while nickel addition improved the hydrogen capacity. Among the additives tested, Zr7Ni10 is the best for optimized hydrogenation kinetics and capacity.

Zr,Ni和Zr-Ni合金的添加对体心立方52Ti-12V-36Cr合金氢吸收的影响
研究了Zr,Ni和Zr 7 Ni 10的添加对体心立方(BCC)52Ti-12V-36Cr的晶体结构,微观结构和氢吸收的影响。我们发现添加Zr和/或Ni导致形成富Ni / Zr的第二相。与裸露的BCC合金相比,该第二相使具有添加剂的合金进行的第一次氢化更快。锆的添加对孵育时间和固有的氢化动力学有积极的影响,而镍的添加则改善了氢容量。在测试的添加剂中,Zr 7 Ni 10是优化氢化动力学和容量的最佳选择。
