This study investigates the effects of the addition of the intermetallic compounds ZrMn2 and Zr7Cu10 to the alloy TiCr1.1V0.9, in terms of the resulting structure and hydrogen absorption/desorption properties. 4 wt % of each intermetallic compound was co-melted into the TiCr1.1V0.9, creating two new alloys. The resulting structure, as studied by X-ray, predominantly exhibited a body-centered cubic (BCC) structural phase coexisting with a C14 Laves phase. A SEM analysis found C14 Laves phase to be distributed at the grain boundaries of the BCC structure. An analysis carried out using Sieverts-type equipment showed that this type of microstructure could be advantageous due to the fact that hydrogen absorption capacity did not decrease with the addition of the intermetallic compounds, in fact, its value increased to 3.85 wt %. Additionally, the structure exhibited fast hydrogen absorption kinetics.

TiCr1.1V0.9合金第一次加氢过程中添加Zr基金属间化合物的影响。

这项研究研究了金属间化合物ZrMn 2和Zr 7 Cu 10加入到TiCr 1.1 V 0.9合金中对产生的结构和氢吸收/解吸性能的影响。将每种金属间化合物的4 wt%共熔化到TiCr 1.1 V 0.9中,制造出两种新合金。通过X射线研究,所得结构主要表现出与C14 Laves相共存的体心立方(BCC)结构相。SEM分析发现,C14 Laves相分布在BCC结构的晶界处。分析进行了使用表明,这种类型的微结构可以是这样的事实,氢吸收能力不与另外的金属间化合物的降低有利的,因为若干希沃特型设备,事实上,它的值增加至3.85重量%。另外,该结构表现出快速的氢吸收动力学。
