【摘要】 本文采用不同轧制变形量热轧制备了界面植入Mn粉和未植入Mn粉的Al/Mg/Al复合板,研究了轧制变形量和植入Mn粉对复合板界面显微组织的影响。结果表明,不同轧制变形量下Al/Mg/Al复合板的界面都结合良好,Mg/Al界面的Mg、Al元素共存区厚度随轧制变形量增加而增加,界面结合效果也有所提高。植入的Mn粉中间层同样有利于Al/Mg/Al复合板界面的结合:Mn粉颗粒以弥散状态分布在Mg/Al界面上,极大提升了界面的复杂性;Mn粉增加了部分Mg/Al界面的变形程度,同时嵌入在Mg层或Al层中,以上现象导致植入Mn粉后界面结合强度提高。更多还原

【Abstract】 This paper studies the effects of different hot rolling deformation amounts and the implantation of Mn powder on the microstructure of the interfaces in Al/Mg/Al composite plate.The results indicate that the interfaces of the Al/Mg/Al composite plates is well bonded under different hot rolling deformation amounts.The thickness of the coexistence zone of Mg and Al elements at the Mg/Al interface increases with the increase of hot rolling deformation amount,and the interfacial bonding effect is also enhanced.The implanted Mn powder is also beneficial to the bonding of the Al/Mg/Al composite plate interfaces:the Mn particles are dispersedly distributed on the Mg/Al interface,which greatly increase the complexity of the interface;Mn particles increase the deformation degree of some Mg/Al interfaces and is embedded in the Mg or Al layers,which is beneficial to the interface bonding strength.更多还原
