摘要

由于熔炼过程中Si含量较高,导致过共晶AlSi合金的机械强度降低,导致初生和共晶Si的激发。适当的微观组织机制和强化材料的夹杂可以克服这一问题。因此,本研究在ADC14过共晶AlSi合金中分别添加5、10和15 wt%的氧化铝,采用搅拌铸造法制备复合材料。研究了AC14复合材料的微观结构、力学和物理特性,并采用表面响应和方差分析方法,通过统计分析考察了变量和响应之间的相互作用,以及贡献的显著性。氧化铝的加入提供了更好的微观结构,并因此提高了机械强度。当氧化铝质量分数为15 wt%时,拉伸强度和硬度最高,分别为85 MPa和44 VHN。计算得到的孔隙率与氧化铝含量成反比。表面响应分析和方差分析结果表明,变量与响应之间具有良好的交互作用,且贡献显著。实验和统计结果表明,氧化铝的加入使ADC14复合材料具有更好的力学性能和微观结构。

Microstructure, mechanical and physical characteristics analysis of ADC14 hypereutectic AlSi composite reinforced with Al2O3
The instigation of primary and eutectic Si has been observed due to the higher content of Si during melting and caused to reduction in the mechanical strength of hypereutectic AlSi alloy. The appropriate mechanism of microstructure and inclusion of strengthening materials can overcome this problem. Thus, in this research work, 5, 10 and 15 wt% of alumina were added in ADC14 hypereutectic AlSi alloy for composite fabrication through stir casting. The microstructure, mechanical and physical characteristics of the AC14 composite were investigated, and the surface response and ANOVA approaches were used to investigate the interaction between variables and responses, and significance of contribution through statistical analysis. The addition of alumina provided better microstructure, and due to it mechanical strengths were improved. The highest value of tensile strength and hardness 85 MPa and 44 VHN respectively were obtained for 15 wt% of alumina. Whereas, the calculated porosity has inverse proportion with the content of alumina. The surface response analysis and ANOVA results showed good interaction between variables and responses, and the contributions were significant. Based on the obtained experimental and statistical results, the addition of alumina provided better mechanical properties and microstructure of the ADC14 composites.
