The explosion energy of RDX-based explosive containing hydrogen storage alloy was studied by underwater explosion and air blast in comparison with that of aluminum-containing explosive.It was found that the hydrogen storage al-loy-containing explosive with appropriate ingredient had higher underwater explosion energy than aluminum-containing ex-plosive when the content of metal was 30%.The explosives containing A-30 and A-60 increased by 9.3%and 5.8%in the bubble-energy,and by 7.0%and 3.0%in the total-energy,respectively.The air blast test demonstrates that the overpres-sure of shockwave of hydrogen storage alloy-containing explosive has no apparent advantage over aluminum-containing explo-sive at the same measuring point.Experiment results indicate that hydrogen element can improve the oxidation of aluminum and boron by releasing heat and steam,and hence increase the overall energy output.%通过水下试验和空中爆炸试验研究了RDX基含储氢合金炸药的能量释放，并与含铝炸药进行比较。水下能量的研究发现，在金属粉质量分数为30％时，组分适当的含储氢合金炸药水下爆炸比气泡能和总能量高于相应含铝炸药，含A-30、A-60合金炸药的比气泡能分别比含铝炸药提高9．3％和5．1％，总能量分别提高7．0％和3．0％；空中爆炸研究发现，在相同爆心距处，含储氢合金炸药的爆炸冲击波压力和冲量与含铝炸药相当。试验结果表明：由于储氢合金中的氢元素能够通过燃烧放热和产生水蒸气并促进铝、硼金属的氧化，因此可以提高爆炸的总体能量输出。
