摘　　要：锆合金具有良好的耐腐蚀性能,采用爆炸焊接法制备的锆/钢复合材料主要用于制造耐腐蚀容器。为验证锆/钢复合材料在制造耐腐蚀容器及容器使用过程中能够满足加工要求和严苛的工况。本研究对锆/钢复合材料进行不同制度的热处理,并对复合材料的力学性能和界面组织进行检测与分析,研究不同热处理制度对锆/钢复合材料的影响。结果表明:锆/钢复合材料通过不同热处理,在500℃保温6 h后,其粘接强度达到最大值245 MPa,在界面处并未发生剧烈反应,在锆/钢材料界面处发现约为2μm的过渡层,其主要元素为Ze、Fe,且元素呈现出梯度分布。锆钢复合材料热处理后其断裂形式为韧性断裂与解离断裂相结合的混合断裂。Zirconium alloy has good corrosion resistance,and Zirconium/Steel composite materials prepared by explosive welding method are mainly used to manufacture corrosion-resistant containers.To verify that Zirconium/Steel composite materials can meet processing requirements and harsh working conditions in the manufacturing and use of corrosion-resistant containers,this study investigates the effects of different heat treatment regimens on Zirconium/Steel composite materials,and tests and analyzes their mechanical properties and interfacial microstructure.The results showed that after different heat treatments and insulation at 500℃for 6 hours,the bonding strength of Zirconium/Steel composite reached its maximum value of 245 MPa,and no violent reaction occurred at the interface.A transition layer of about 2μm was found at the interface of Zirconium/Steel material,with the main elements being Zr and Fe,and the elements showed a gradient distribution.The fracture mode of zirconium steel composite material after heat treatment is a mixed fracture combining ductile fracture and dissociation fracture.
