Effects of Forging on Properties of Self-Propagating High-Temperature Synthesized Alloys for Vanadium-Based Hydrogen Storage Batteries

In order to explore the effect of forging on the properties of self-propagating high-temperature synthesized alloys for vanadium-based hydrogen storage batteries of new energy vehicles and improve their comprehensive properties, the samples of self-propagating high-temperature synthesized V₃TiNi_0.56vanadium-based hydrogen storage alloys were forged, and the microstructure, charge-discharge cycle stability and alkali corrosion resistance of the sample were also tested and analyzed.The results show that forging reduces the average grain size of the self-propagating high-temperature synthesized V₃TiNi_0.56vanadium-based hydrogen storage sample by 65.38%, the discharge capacity decay rate is decreased by 91.08%,and the positive shift of corrosion potential is 19.24%, which significantly improves the charge discharge cycle stability and alkali corrosion resistance of the alloy.
