冷锻紫铜药型罩材料的织构研究

Study on Textures of Cold-forging Pure Copper Shaped Charge Material

运用X射线衍射仪对两种铜药型罩材料进行了织构测量和分析，研究不同的加工工艺对铜药型罩材料的显微组织及织构的影响，结果表明，冷锻罩晶粒细小，具有均匀弱织构，各向同性好，而挤压罩织构较强，呈现明显的各向异性，两罩沿母线方向的各向异性程度均大于沿周向的，且罩底各向异性程度最大，罩底的织构沿周向挤压罩的差别大，冷锻罩的差别小；两罩罩体上下部分织构差别依次减弱，即挤压罩差别较大，冷锻罩底和罩顶织构相差最小。靶试结果表明，冷锻罩具有高的破甲性能。

Texture measurements and analyses of two kinds of copper shaped charge liners have been conducted by X-ray diffraction. The effects of different processings on microstructures and textures of shaped charge liners have been studied. The results show that the cold-forged liners with fine grains possess homogeneous weak textures and good isotropy, but the extru- ded ones has stronger textures and obvious anisotropy, the anisotropy of both shaped charges along generatrix is stronger than that along periphery, and the anisotropy of the bottom of liners is the strongest,textures of the bottom of extruded ones along periphery have greater difference than that of cold-forged ones. Textures of both become weaker and weaker from bottom to top, that is, the former has much greater difference, and textures of the bottom and the top of the latter have a little difference. The firing results show that cold-forged liners present very high penetration performances.
