综述了爆炸焊接工艺对金属力学性能的要求.指出这种要求主要体现在金属的强度或塑性、以及它们的冲击韧性值上.为了易于爆炸焊接和获得相对结合强度较高的复合材料,可以选择强度较低或塑性较高的金属基村;为了避免它们在爆炸焊接过程中开裂和脆断,金属的a_K(或A_K)值不宜太小.这两种力学性能指标在爆炸焊接中的作用和影响是不一样的. In this paper, the requirements of the mechanical properties of the explosive welding process are reviewed, and it is pointed out that this requirement is mainly reflected in the strength or plasticity of the metal and their impact toughness values. To facilitate the explosive welding and to obtain the composite material with higher relative bonding strength, In order to avoid their cracking and brittle fracture, the value of a_K (or A_K) of metal should not be too small. The role of these two kinds of mechanical properties in explosive welding and The impact is different.
