摘要: 采用不同的爆炸焊接工藝爆炸復合了鋁合金/純鋁/鋼與鋁合金/鋼/鋼復合板,并對其結合界面形態進行了顯微觀察與分析,測量了爆炸焊接界面的波形參數,探討了不同爆炸焊接工藝及不同材料對爆炸復合界面波形參數的影響.結果表明:爆炸焊接界面波形受爆炸焊接工藝及材料性能的影響,當基、復板材料性能相差較大時,易形成平直界面,波形不明顯;當基、復板材料相同或相近時,界面易形成有規律的正弦波形.當焊接材料相同時,隨著爆炸焊接裝藥密度的增加,界面波長、波高均有所增加.Abstract: Aluminum alloy/aluminum/steel and aluminum alloy/steel/steel cladding plates were exploded by different explosive welding technologies. The bonded interface's configuration was observed and analyzed, and the wave parameters were measured by optical microscope. The results show that the wave configuration of the bonded interface depends on the explosive welding technology and material properties. A line-straight bonded interface formed when the properties of the base plate and flyer plate were greatly different. However, a regular sine wave shape was easily generated when the base plate and flyer plate were the same or their properties were similar. The wave length and the wave amplitude become bigger with increasing explosive density.
