摘要: 采用累积叠轧(Accumulative roll bonding,ARB)制备AX10/ZK60层状异构复合材料,研究累积叠轧道次对复合材料微观组织与力学性能的影响。结果表明:随着ARB道次的增加,抗拉强度和屈服强度逐渐上升,断裂总先上升后下降,但未发生明显下降。ARB第6道次的力学性能达到最佳,抗拉强度、屈服强度和断裂总分别为274 MPa、240 MPa和13.9%。材料强度的提高归因于细晶强化和第二相强化的协同作用,断裂总的提高是层间结构界面产生背应力引起的。硬度整体呈现升高趋势,这是因为ARB过程中产生的大量位错增强了材料硬度,但第5、6道次的硬度出现波动,这是由动态再结晶效应及大量亚结构的形成导致的。

Abstract: AX10/ZK60 layered heterogeneous composites were prepared by accumulative roll bonding (ARB), and the effect of cumulative rolling passes on microstructure and mechanical properties was studied. The results show that with the increase of ARB passes, the tensile strength and yield strength increase gradually, and the elongation increases first and then decreases, but no significant decrease occurs. The mechanical properties reach the best at the 6th pass, with the tensile strength, yield strength and elongation of 274 MPa, 240 MPa and 13.9%, respectively. The increase in the strength of the material is attributed to the synergistic effect of fine-grained strengthening and secondary phase strengthening. The increase in elongation is caused by the back stress at the laminated structural interface. The overall hardness shows an increasing trend, which is due to the large number of dislocations generated in the ARB process to enhance the hardness of the material, but the hardness at the 5th and 6th passes fluctuates, which is caused by the dynamic recrystallization effect and the formation of a large number of substructures.

Key words: accumulative roll bonding, laminated composites, back stress, dynamic recrystallization, work hardening
