摘　　要：通过水下试验测试了含硼铝、硼镁、硼镁铝合金、硼钛、硼锆等混合金属粉炸药的水下能量,并与相应含铝炸药的水下能量进行了对比。结果发现,以HMX为基金属粉的质量分数20%时,镁粉、镁铝合金与硼粉混合后水下总能量比单独使用硼粉时约提高40%;含硼铝质量分数20%的炸药的水下总能量比含铝质量分数20%炸药高约7%;以RDX为基,含硼铝、硼镁、硼镁铝合金质量分数20%炸药的水下总能量比含铝20%的炸药均有提高,其中硼镁达到9%。随着硼铝金属粉含量的增加,水下总能量不断提高,均高于相应含铝炸药,当硼铝金属粉质量分数为35%时达到最高,比含铝35%炸药约高7%,含量40%后开始降低。硼粉与铝粉混合使用,可提高硼粉氧化效率和炸药水下总能量。By underwater experiment, the underwater energy of explosives containing boron and combustible metals, including aluminum,magnesium, magnesium-aluminum, magnesium titanium and magnesium zirconium,is tested and compared with aluminum-containing explosive. Results show that the overall energy of HMX-based explosives containing 20% boron-magnesium and 20% boron-magnesium-aluminum is 40% more than that of HMX-hased explosive with 20% boron. The energy of 20% boron-aluminum-containing HMX-based explosive is 7% more than that of 20% aluminum-containing HMX-based explosive. The RDX based explosives containing 20% boron-aluminum, 20% boron-magnesium and 20%; boron-magnesium aluminum have higher overall energy than 20% aluminum-containing RDX based explosive, 9% higher with boron-magnesium. The overall energy of RDX -based explosive becomes higher with the increase of the content of boron-aluminum. When the content reaches 35%, the overall energy reaches tiptop, almost 7% higher than 35% aluminum-containing explosive. When the content reaches 40%, the overall energy becomes lower. When boron is blended with aluminum, its oxidizing efficiency and overall energy of metalized explosive can be improved.
