| 摘 要： | 研究了快淬作用对Ti-28V-15Mn-10Cr合金的相结构和储氢性能的影响。XRD实验结果表明，快淬处理使得合金由BCC和C14Laves两相结构转变为单一的BCC相结构，同时合金的晶格常数随着快淬冷速的增加而增大。快淬作用能显著改善Ti-28V-15Mn-10Cr合金的吸放氢平台特性，从而导致合金放氢量的增加。然而，快淬处理也使得合金的放氢平台压下降以及活化性能变差。

| Abstract: | The effect of rapid quenching on phase structure and hydrogen storage performance of Ti-28V-15Mn-10Cr alloy is investigated. X-ray diffraction (XRD) results show that two phases of BCC and C14 Laves of the as-cast alloy are transformed into a single BCC phase after rapid quenching treatment. The lattice parameters of the alloy increase with increasing of quenching rate. It results in a flatter hydrogen absorption-desorption plateau and a lower hydrogen absorption-desorption plateau pressure. With increasing quenching rate,the activation of Ti-28V-15Mn-10Cr alloy becomes worse. |
