Research on Computer Optimization of Low-Cost Hydrogen Storage Alloy Containing Boron Prepared by Strip Casting and its Microstructure and Performance

摘要

A kind of low-cost hydrogen storage alloy containing boron has been prepared by near rapid solidification strip casting. And computer optimization has been carried out 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 CeCo{sub}4B on the crystal interface, which increases the diffusion channels for hydrogen atoms and improves the alloy activation. The MmNi{sub}3.9Co{sub}0.37Mn{sub}0.4Al{sub}0.3B alloy has excellent performance at room, high and low temperatures prepared by strip casting.
