High-vanadium BCC type alloy and preparation method thereof

The invention discloses a high-vanadium BCC type alloy and a preparation method thereof, the general formula of the alloy is TiaCrbVcFedLe, in the formula, a, b, c, d, e and f represent weight percentages, and the numerical ranges of a, b, c, d, e and f are as follows: 8% < = a < = 20%, 2% < = b < = 20%, 48% < = c < = 63%, 10% < = d < = 17%, and 5% < = e < = 10%. The maximum hydrogen absorption amount of the alloy is 3.83 wt%, and the maximum hydrogen desorption amount of the alloy is 2.72 wt%. According to the scheme, raw materials are placed in a medium-frequency induction melting furnace, vacuumized, dried and smelted in an inert atmosphere; and molten alloy liquid is poured on quenching melt-spinning equipment under the protection of inert atmosphere to be cooled, the hydrogen storage alloy sheet is successfully prepared, and the problem of poor performance caused by component segregation in the pouring and cooling process is solved. 本发明公开了一种高钒BCC型合金及其制备方法，合金的通式为TiaCrbVcFedLae，式中，a、b、c、d、e、f表示重量百分比，其数值范围为
