| 摘 要： | 采用累积叠轧焊+中间退火法复合轧制1060Al/Fe基非晶多层铝合金复合板材。利用光学显微镜、扫描电镜、X-衍射分析仪以及拉伸试验机分析Al基复合材料的微观组织结构变化、断口形貌、物相组成以及力学性能。结果表明:Fe基非晶复合材料的增强体在300 ℃中间退火过程中发生部分晶化,在累积变形轧制过程中发生破碎,并随着变形道次的增加,破碎程度随之增大;复合板前6道次的累积轧制变形出现了明显的加工软化现象,并且随着变形道次的增加,其加工软化的效果愈明显;随着累积轧制变形道次增加,Al基复合材料的力学性能发生了明显的变化,第2道次轧制变形后屈服强度与抗拉强度达到了最大值为140 MPa和156 MPa,伸长率为5.53%,达到最佳综合性能。

| Abstract: | 1060 Al/Fe-based amorphous alloy multi-layered composites were prepared by means of accumulative roll bonding and intermediate annealing. The microstructure, fracture morphologies, phases and mechanical properties of the Al-based composites were analyzed by using optical microscope, scanning electronic microscope, X-ray diffraction and tensile test. The results show that the Fe-based amorphous alloy undergoes partial crystallization during the intermediate annealing process at 300 ℃, and breaks up during the cumulative deformation rolling process, and the degree of breaking up increases with increasing rolling deformation passes. The composite plates softens evidently in the first 6 passes of cumulative deformation rolling, the softening effect is more obvious with the increasing passes. With the increase of accumulated rolling deformation passes, the mechanical properties of Al-based composites have changed obviously. After the second rolling deformation, the yield strength and tensile strength of the composites reach the maximum values of 140 MPa and 156 MPa respectively, and the elongation is 5.53%, reaching the best comprehensive properties. |
