摘　　要：对在相同爆炸复合条件下几种不同状态的金属所产生的绝热剪切带(ASB)的显微组织进行了观察及显微硬度测定,探讨了不同的相组成、预变形程度和晶体结构对绝热剪切带形成的影响。结果表明:ASB的形态、大小和数量受材料的预冷变形程度、成分、晶体结构、相组成等因素的影响;ASB的硬度值均高于基体。This work investigated the effects of the metallurgical parameters on the forming of adiabatic shear bands (ASBs) in some different state metals under the same explosive cladding process by observing microstructures and measuring microhardness. The results indicated that the shape, size and quantity of ASBs are affected by the factors of pre-deformed degree,. crystal structure, phase states etc. The micro-hardness of ASB is higher than that of the matrix.
