摘要

以硅溶胶搭载SiC增强体的混合浆料表面涂覆为辅助

采用层叠热轧工艺制备SiC+SiO

sol-Al层状复合板

并对其显微组织与力学性能进行研究。结果表明

SiC+SiO

sol-Al层状复合板界面结合良好

层间结合处SiC颗粒呈断续状均匀分布于铝箔基材间层

表面覆有SiO

和微量Al

这有利于界面载荷传递且使铝箔基材层的晶粒尺寸更细小和均匀。断裂机制为单相铝箔层韧性断裂与层间脱粘撕裂。与纯铝箔叠轧的纯Al层状复合板相比

其抗拉强度提高

伸长率下降。

Abstract

Assisted with the surface coating of the mixed slurry of silica sol carrying SiC reinforcement

the SiC+SiO

sol-Al composite sheet was fabricated by laminating hot rolling

and microstructure and mechanical properties of the composites were investigated.The results indicate that the interface in SiC+SiO

sol-Al composite sheet is well bonded and the surface is covered with a certain amount of SiO

and a small amount of Al

. The introduced SiC particles are intermittently and evenly distributed in the interlayer of the aluminum foil substrate

which is conducive to interfacial load transfer and makes the grain size of the aluminum foil in SiC+SiO

sol-Al composite sheet more refine and uniform.The fracture mechanism is characterized by ductile fracture and delamination tearing of single-phase aluminum foil substrate layer.Compared with the pure-Al laminated plate

the tensile strength of the composite is increased and the elongation is decreased
