研究氮含量为0.56%的不同厚度规格的高氮奥氏体装甲钢抗穿、破甲弹侵彻时的抗弹性能、冲击硬化、抗弹机理等现象,以防护系数的优劣作为评定依据.试验结果表明,高氮钢可产生明显的冲击硬化现象,具有优良的抗弹性能和综合性能,高的防护系数使其可作为优良的防护材料.

The ballistic behavior,impact hardening and ballistic mechanism of high nitrogen austenitic armor steel with nitrogen content of 0.56% against penetrator and high explosive anti-tank (HEAT) were investigated. The protection efficiency was used as criterion. The experimental result shows that high nitrogen steel possesses excellent ballistic property and comprehensive property, and obvious impact hardening. High protection efficiency is qualified as a good protection material.
