采用累积叠轧焊法制备了Al/AZ31多层复合材料,并通过扫描电镜、X射线能谱仪和显微硬度计对所制备的Al/AZ31多层复合材料进行了横截面形貌观察、能谱分析以及显微硬度测试.结果表明,经过三道次的累积叠轧焊之后可制备Al/AZ31多层复合材料.能谱分析表明,在Al层和AZ31层的界面处产生了扩散层.随着轧制道次的增加扩散层的厚度逐渐增加.显微硬度测试表明,随着轧制道次的增加,Al/AZ31多层复合材料的层组元的强度也随之增加,但Al层的强度较AZ31增加得快,并且形成的界面扩散层具有一定的硬度梯度. |

Al/AZ31 multilayered composite was fabricated by ARB process. A scanning electron microscope (SEM ) equipped with energy dispersive X-ray spectrometer ( EDS ) was used for the observation of the cross-section of the ARB processed Al/AZ31 multilayered composite. The micro-hardness of the cross-section was also measured. SEM observation of the cross-section showed that Al/AZ31 multilayer compos-ite could be fabricated successfully.EDS line-scan a-nalysis indicated that there was diffusion layer at the interface between the Al layer and AZ31 layer and the thickness of the diffusion layer would be thicker and thicker with the increase of the ARB cycles. The strength of the Al and AZ31 layers would also increase, and there was gradient hardness at the Al/ AZ31 interface diffusion layer. |
