在300,350,400℃下成功通过挤压复合法制备多层AZ91-(SiCP/AZ91)复合板,探究AZ91-(SiCP/AZ91)复合板中SiCP/AZ91复合材料层和AZ91层的显微组织演变、界面的演化机制和力学性能变化规律。结果表明:热挤压复合中,AZ91-(SiCP/AZ91)多层复合板中合金层发生完全动态再结晶,晶粒细化,合金组织随挤压温度的升高更均匀,而且外层合金层比内层合金层晶粒尺寸略大;SiCP/AZ91复合材料层同样发生完全动态再结晶,晶粒尺寸小于合金层,随着挤压温度的升高,SiCP的分布更加均匀;不同挤压温度下AZ91-(SiCP/AZ91)复合板合金层与复合材料层界面均未出现明显的分层以及开裂现象;AZ91-(SiCP/AZ91)复合板的室温力学强度位于AZ91合金与SiCP/AZ91复合材料之间, SiCP/AZ91层中SiCP与基体界面脱粘是导致复合板材失效的主要原因。 |

Multilayered AZ91-(SiCP/AZ91)clad plates were fabricated at 300,350 ℃ and 400 ℃ successfully by extrusion.The microstructure evolution,bonding interface and the mechanical properties of the AZ91-(SiCP/AZ91)clad plates were investigated in detail.The results show that grain of both of the AZ91layer and SiCP/AZ91layer are refined due to the dynamic recrystallization (DRX)during the extrusion processes and the SiCP/AZ91layer processes much finer grain size.The SiCPdistribution of SiCP/AZ91layer is improved with increasing of extrusion temperature.No obvious delamination is observed in the AZ91-(SiCP/AZ91)clad plates fabricated at different temperatures.The metallurgical bonding of the interface between AZ91and SiCP/AZ91basically occurs in the extrusion die.The room-temperature strength of the AZ91-(SiCP/AZ91)composite lies between the AZ91alloy and the SiCP/AZ91,corresponding well with the rule of mixture(ROM). The inadhesion of the SiCPin the SiCP/AZ91layer is the main reason for the failure of the AZ91-(SiCP/AZ91)clad plates during tensile test. |
