摘要
自制X值不同的Ti_(0.7)Zr_(0.3)(Cr_(1-x)V_x)_2合金,采用XRD和SEM对其成分及组织进行分析,同时利用Sieverts仪器测量结合贮氢量和贮氢密度数学计算模型,绘制合金的吸氢活化性能和压力-浓度-温度曲线。结果表明,Ti_(0.7)Zr_(0.3)(Cr_(1-x)V_x)_2合金为复杂的多相组织,由Laves相和不同晶格常数的bcc固溶相组成;合金具有较好的活化性能和抗氧化性能;随着V元素含量的增加,合金的贮氢含量增加,放氢含量减小。
The Ti0.7Zr0.3（Cr1-xVx）2 alloy was developed, and the composition and microstructure were analyzed using XRD and SEM. Meanwhile, the Sieverts apparatus was used to measure the alloy hydrogen activation absorption performance and pressure-temperature-concentration curve. The results show that the crystal structure of the Ti0.7Zr0.3（Cr1-xVx）2 belongs to a complicated muff-phase structure, which are composed of two Laves phase and some bee solid solution phase with different lattice constants; these alloy have good activation properties and oxidation resistances; with the increase of V element content, the hydrogen storage ability of the alloy increases.
