Abstract
The objective of this study was to investigate the influence of bimodal reinforcement on the fluidity and mechanical properties of SiC particle reinforced AZ91D Mg composites. The fraction of bimodal SiC particles was fixed at 20 wt% and the mixing ratios of 5 ㎛ to 50 ㎛ SiC particles were 0:1, 1:2, 1:1, 2:1 and 1:0. The results clearly showed that the fluidity and mechanical properties of the composites with bimodal reinforcement were dependent on mixing ratio. In terms of molten state fabrication and tailored mechanical properties, it was obtained that the proper mixing ratio seems to be 1:2.
