为了研究高强度装甲钢的穿甲破坏机理，采用１２．７ｍｍ弹道枪垂直射击１５ｍｍ厚的Ｍｎ－Ｃｒ－Ｎｉ－Ｍｏ－Ｂ高强度装甲钢板，弹丸速度在３５０～５００ｍ／ｓ内变化。分析了绝热剪切带的产生及其对冲塞穿甲的作用。试验结果表明，当弹靶参数一定时。高强度钢板中易发生由绝热剪切导致的冲塞穿甲。由微观组织和硬度测试证明绝热剪切带是一种转变带。转变带内的裂纹和沿转变带扩展的裂纹对装甲钢的破坏影响极大。
In order to study the perforation failure mechanism of high strength armor steel, a 12.7mm ballistic gun was used to vertically shoot a 15mm thick high strength armor plate of Mn-Cr-Ni-Mo-B. The projectile velocity varied from 350 to 500m / s. The production of adiabatic shear band and its effect on puncture and penetration are analyzed. Experimental results show that when the target parameters of a certain time. High-strength steel prone to adiabatic shear caused by puncture piercing. Microstructure and hardness tests show that adiabatic shear band is a kind of transition band. The transformation of the crack in the zone and the crack propagating along the transition zone have a great impact on the destruction of the armored steel.
