钛/不锈钢复合板界面分析及性能研究

Study on Interface Morphology and Properties of Titanium/Stainless Steel Composite Plate

研究了厚复层TA1/304复合板沿着爆轰波传播方向、距离起爆端不同位置处的焊接界面变化情况,通过金相分析及性能检测将复合界面的变化情况进行了整体分析,系统研究了在爆轰波传播过程中,界面的动态变化过程。结果表明:沿着爆轰波传播方向,焊接界面形态经历了无波,成波,波幅、波长增大,稳定至消失的动态变化过程。伴随着界面形态的改变,剪切强度先增加随后稳定,最终在起爆对边位置强度明显降低,剪切强度最低为230 MPa。在距起爆边300~400 mm处,界面波形态稳定,波幅比为0.22,剪切强度约为450 MPa。

Here were studied the variation of the welding interface of thick laminated TA1/304 composite plate at different positions from the initiation end along the detonation wave propagation direction.The variation of the composite interface was analyzed as a whole through metallographic analysis and performance detection,and the dynamic change of the interface was systematically studied during the detonation wave propagation process.The results indicated that along the propagation direction of detonation wave,the welding interface morphology experienced the dynamic change process of no wave,wave-forming,amplitude and wavelength increasing,wave stabilizing and wave vanishing.With the change of interface morphology,the shear strength first increased and then stabilized,and finally significantly decreased at the position opposite to the initiation,with the lowest shear strength of 230 MPa.In the range of 300~400 mm from the detonation edge,the interface wave was stable in shape,with the wave amplitude ratio of 0.22 and the shear strength of about 450 MPa.
