准晶是一种结构特殊的固态有序相.其特殊的原子排列方式可能会使其具有较高的储氢性能.研究目的是获得Ti系准晶,并对其电化学储氢性能进行研究.采用铸造法炼制合金,准晶难以形成.因此采用首先通过机械合金化获得非平衡态合金,然后对非平衡态合金进行不同温度热处理来获得准晶的技术路线.采用机械合金化制备了Ti42.5 Zr42.5 Ni15非晶.在机械合金化过程中要注意气体保护,否则难以形成非晶.将非晶合金在530℃处理2h后,在基体中出现了准晶,此时的基体为准晶和晶态混合物,准晶占大部分.经750℃处理2h后,合金基体中只有晶态存在.对不同状态合金进行了电化学储氢特性测量.对于非晶、准晶、晶态三状态合金,其电化学储氢均存在一个活化过程.非晶态的容量最高,其次为准晶态,晶态最低.
