摘要
为探究不同炸药厚度、靶材间距及基座类型对爆炸焊接复合板抗拉性能的影响,通过平行爆炸焊接法制备了不锈钢/铝/不锈钢/铝/不锈钢5层复合板,使用万能试验机测试了复合板准静态拉伸性能。研究结果表明:通过爆炸焊接法使材料屈服强度提高了1.34倍;20mm装药厚度已达到爆炸焊接能量上限,继续提升装药厚度不影响复合板抗拉性能;使用砂土作为基座不影响复合板的抗拉性能;提升靶材间距使复合板屈服强度和抗拉强度分别提高了24.3%和11.3%。研究表明爆炸焊接法是一种良好的提升材料抗拉性能的手段。
In order to explore the influence of different charge heights,target spacing and pad types on the tensile properties of explosive welded composite plates,a five-layer composite plate made of stainless steel/aluminum/stainless steel/aluminum/stainless steel was prepared by parallel explosive welding method,and the quasi-static tensile properties of the composite plate were tested by universal testing machine.The results show that the yield strength of the material is increased by 1.34 times by explosive welding.The charge height of 20 mm has reached the upper limit of explosive welding energy,and the tensile property of composite plate will not be affected by increasing the charge height.The use of sand as backing plate does not affect the tensile properties of composite plates.The yield strength and tensile strength of the composite plate are increased by 24.3%and 11.3%respectively by increasing the target spacing.Explosive welding is a good method to improve the tensile properties of materials.
