系统地研究了钛锰二元合金的吸、放氢量,压力组成等温线以及吸氢过程热力学函数(ΔHΔS)的变化。实验证实,对于不加均匀化退火和活化处理的二元钛锰合金,其综合吸放氢性能最佳的组成为TiMn_(1.15)-TiMn_(1.25)。
The changes of the adsorption and desorption amounts, the pressure composition isotherms and the thermodynamic functions (ΔHΔS) of hydrogenation of Ti-Mn binary alloys were studied systematically. The experimental results show that TiMn_ (1.15) -TiMn_ (1.25) is the best composition for the hydrogen storage and desorption of binary Ti-Mn alloys without homogenization annealing and activation treatment.
