摘要
随着爆炸焊接技术的发展,锆-钢复合板作为一种特殊的耐蚀复合材料,结合了锆优良的耐蚀性能和钢的高强度的优点,在工业中的需求量也逐步增加.以爆炸焊接理论为基础,采用数值模拟和试验分析相结合的方法,在ANSYS/LS-DYNA软件中模拟R60702/TAI/16MnⅢ复合板不同间隙值组合下爆炸焊接的动态过程.分析间隙值对整个R60702/TAI/16MnⅢ复合板爆炸焊接成形的影响.结果表明,当锆-钛间距/钛-钢间距取值为12/6 mm时,可以实现良好焊接.对试验焊接后R60702/TAI/16MnⅢ复合板上不同位置处的试样进行扫描电镜分析,观察复合板界面的结合状况,为选择更合适的工艺条件提供数据支撑,有利于指导生产实践.
With the development of explosive welding technology,the demands of explosive welding of Zr/Steel plate are increasing.Composite plate of the Zr/Steel,as a specific anti-corrosion composite material,possesses the combined characteristics of the excellent corrosion resistance property of zirconium and the high-strength property of steel.Based on the theory of explosive welding,the dynamic process of the explosive welding was simulated by ANSYS/LS-DYNA software.The influences of gap values on welding joint formations of the R60702/TAI/16MnIII metal sheets were analyzed.The results showed that when the assorted gaps among zirconium and titanium/titanium and steel were12mm and6mm,the welding quality was favorable.Interfacial bonding of the R60702/TAI/16MnIII composite material obtained by explosive welding experiment was studied by a scanning electron microscope.These experimental data could be used to choose the suitable technical conditions,which was beneficial to guiding production practice.
