在40℃及初始氢气压力为4MPa条件下,测定了TiMn_(1.5-x)Cr_x合金的首次吸氢动力学曲线,并在19℃测定了TiMn_(1.5-x)Cr_x-H体系的放氢压力-组成等温线。结果表明,用Cr取代TiMn_(1.5)合金中部分Mn时,缩短孕育期,提高吸氢速率,增加吸氢量,放氢量也有一定增加,改善了合金贮氢性能.
The first hydrogen absorption curves of TiMn_(1.5-x)Cr_x have been determined at 40℃ and an initial hydrogen pressure of 4.05MPa. Pressure-composition desorption isotherms for TiMn_(1.5-x)Cr_x-H system have also been determined at 19℃. The results show that hydrogen storage properties improve markedly while Mn was partially substituted by Cr: reducing the VIZ incubation period, enhancing the absorption rate, increasing the absorption capacity and slightly raising the desorption amount of hydrogen.
