摘要

通过实验和 JMatPro® 计算，研究了载荷比 (R) 对低碳钢/2 级钛炸药复合材料界面微观结构和相稳定性的影响。在低冲击能量条件下（即 R = 1.07），界面呈现对称的波浪状形态，熔融金属被夹杂在波浪漩涡中的孤立区域；而在高冲击加载条件下（R = 3），界面具有复杂的焊接凝固结构，包括平面界面、柱状和等轴树枝状。根据这项研究得出的结论是，在高冲击加载条件下，爆炸包层的界面微观结构将类似于熔焊接头，但相互作用区的厚度相对较低。

Effect of Impact Energy on the Interface Microstructure of Explosively Clad Mild Steel and Titanium

Effect of load ratio (R) on the interface microstructure and phase stability was investigated in mild steel/Grade-2 Ti explosive clads using experimental and JMatPro® computations. At low-impact-energy conditions (i.e., R = 1.07), the interface exhibited a symmetrical wavy morphology with molten metal entrapped in isolated regions within the vortices of the waves, while at high-impact loading conditions (R = 3) the interface had complex weld solidification structure consisting of planar interface, columnar and equiaxed dendrites. Based on the study, it was concluded that under high-impact loading conditions, the interface microstructure of the explosive clads will resemble fusion welded joints, but with relatively lower thickness of the interaction zones.
