摘要：

The influences of misch metal (Mm) on the hydrogen storage properties of FeTi1. 3 alloy have been studied in detail. The results show that the activation behavior of the alloy can be improved dramatically when a small quantity of Mm is added. It suggested that this activation behavior is due to the cracks, which was produced in the FeTi matrix by the expansion of misch metal inclusions coming from preferential hydrogen absorption. As a result, FeTi phase with fresh oxide-free surfaces through which hydrogen can be absorbed easily is provided. In addition, hydrogen storage properties of alloy can be influenced by Mm content. The results show that the overall hydrogen storage properties of FeTi1.3 + 6. 0% Mm alloy are the best among all alloys studied.
