Ta—10W衬管与钢管段的爆炸复合

Explosive Clad of Ta-10W Liner Tube and Steel Tubular Sections

研究了Ｔａ－１０Ｗ合金衬管与ＣｒＮｉＭｏ钢管段的爆炸复合。观察了爆炸复合界面，讨论了装药量与管段变形量的关系，分析了爆炸复合对管段力学性能的影响。结果表明，取相同条件下平板复合炸药厚度的６０％左右作为圆管内复工艺参数的方法是可行的，在装药质量比Ｒ＝０．８条件下，已将０．４ｍｍ厚Ｔａ－１０Ｗ合金衬管可靠地内复在ＣｒＮｉＭｏ钢管段内，结合界面是波状结合。

he explosive clad of Ta-10W liner tube and CrNiMo steel tubular sections has been studied. The interfaces of explosive clad have been examinated also. The relationship between explosive charg and deformation of tabular section is discussed. The effect of explosive clad on mechanical properties of tabular sections is analysed. The optimun process parameters of explosive clad are determined. The results show that the corrected optimum process parameters of explosive clad for plate can be used for explosive clad of inner liner tube. The thickness of explosive charge for explosive clad of tube with circular cross-section is about 60% of that for explosive clad of plate under the same conditions. Ta-10W liner tube of 0.4mm wall can be claded with inner wall of CrNiMo tube under the condition of explosive charge mass ratio R of 0.8. The interfaces of explosive clad are wavelike.
