铀合金的冶金性能良好,易于加工,又可获得高强度与高塑性,有利于侵彻多层装甲,而且具有燃烧后效,所以,美国一些研制中的大口径超速脱壳穿甲弹以及小口径穿甲弹正在研试采用铀合金弹心(表1)。美国研制和应用的贫铀弹心材料主要是铀-0.75％钛合金,用于制造25毫米链式炮和GAU-8式30毫米航炮的穿甲弹弹心及各种型号的大口径超速尾翼稳定脱壳穿甲弹弹心。目前铀钛合金在30毫米航炮 Uranium alloy metallurgy performance is good, easy to process, but also to obtain high strength and high plasticity, is conducive to penetration of multi-layer armor, and has a burning effect, so some of the United States developed a large diameter speeding armor-piercing shells and small- Uranium alloy bombing is being studied (Table 1). The depleted uranium bulletproof materials developed and applied by the United States are mainly uranium-0.75% titanium alloy, armor-piercing bullet cores for manufacturing 25mm chain guns and GAU-8 30mm cannon, and stable shelling of various types of large- Armor bombs Currently uranium titanium alloy gun at 30 mm
