| 摘 要： | 利用直流电铸法制备纯镍药型罩,对其爆炸变形前后的微观组织和织构进行对比观察,探讨电铸镍药型罩爆炸变形后侵彻体的高速变形行为.结果表明,电铸镍药型罩的晶粒形态由变形前的柱状晶转变为等轴晶,变形前存在的微观织构消失.侵彻体在高速变形过程中经历的是绝热变形过程.侵彻体与靶体的相互作用促使射流发生融化,并与靶体熔融形成铁镍合金.熔融的铁镍合金与侵彻体后续跟进的杵体发生接触,在杵体外部边缘部位凝固,生成复合组织.杵体在整个变形过程中经历了典型的动态回复和动态再结晶过程.

| Abstract: | The pure nickel liner of shaped charge was prepared by using a direct current electroforming technique.The high speed deformation mechanism of the jet formed by explosive detonation in the electroformed nickel liner of shaped charge was discussed by comparing the microstructure and microtexture of the nickel liner of shaped charge before and after explosive detonation.Experimental results show that the original grains with a columnar shape change to equiaxed grains and fibber textures existed in the nickel ... |
