The effect of heat treatment on the first hydrogenation of body centred cubic (BCC) Ti₅₂V₁₂Cr₃₆ alloy was investigated. It was found that, after a 1 week heat treatment at 1273 K, BCC phase abundance was greatly reduced by heat treatment. The crystal structure changed from BCC to a complex multiphase pattern of BCC phase, C15-type Laves phase, and α-Ti. The network of the α-Ti phase was broader after heat treatment. The heat treatment eliminated the incubation time of the first hydrogenation and improved the kinetics, but the total hydrogen capacity was reduced by 30%.

热处理Ti ₅₂ V ₁₂ Cr ₃₆合金的晶体结构，显微组织和氢化行为的研究

研究了热处理对体心立方（BCC）Ti ₅₂ V ₁₂ Cr ₃₆合金第一次加氢的影响。发现在1273 K下进行了1周的热处理后，通过热处理大大降低了BCC相的丰度。晶体结构从BCC转变为BCC相，C15型Laves相和α-Ti的复杂多相模式。热处理后，α-Ti相的网络更宽。热处理消除了第一次氢化的保温时间并改善了动力学，但总氢容量降低了30％。
