Abstract
China low activation martensitic steel/aluminum clad tubes were prepared by explosive bonding method in order to study its microstructure characteristics at the interface and to evaluate its performance. The interface morphology of the different parts of the clad tube was characterized by scanning electron microscope and energy dispersive spectroscopy. Then, the performance of the clad tube, including its bonding strength and formability, was investigated. Microstructural results showed that existence of an under-fusion area at the head of the clad tube, diffusion of elements, and the metallurgical bonding was observed in the middle part while cracks and crushing particles appeared at the end of the clad tube. No separation after the cold extruding and hydroforming process showed that the middle part of the clad tube had excellent bonding properties and could endure the second plastic deformation.
