Abstract

A kind of low-cost hydrogen storage alloy containing B has been prepared by near rapid solidification strip casting. And computer optimization has been carried out with MASTER software through mode identification and neuro-network. The alloy microstructure, the alloy performance and the battery performance have been evaluated through optical microscope, TEM and X-ray diffraction. The results indicate that the alloy microstructure is fine columnar crystal and there exists the second phase of CeCo4B on the crystal interface, which increases the diffusion channels for hydrogen atoms and improves the alloy activation. The MmNi3.9Co0.37Mn0.4Al0.3B alloy has excellent performance at room, high and low temperatures prepared by strip casting.
