摘要
本研究探讨了添加 10 wt% Zn 对 Al12Si EN AC 44100 合金微观结构和性能的影响。为此,采用永久模铸造法制造了 EN AC 44100 和 EN AC 44100 + 10 wt%Zn 合金。采用标准金相技术进行了微观结构检测。通过能量色散光谱和 X 射线衍射分析确定了微结构中的相。合金的屈服强度、极限拉伸强度和断裂伸长率是在测量其布氏硬度后通过拉伸试验确定的。使用球盘式磨损试验装置检测了合金的摩擦学特性。结果表明,EN AC 44100 合金的微观结构由富铝α相、原始硅相和β(Al-Fe-Si)相以及共晶硅颗粒组成。添加锌后,EN AC 44100 合金的硬度和强度显著提高,但其摩擦系数和磨损量却因微观结构的改变而大大降低。这种改性导致 α 晶粒和共晶硅颗粒的尺寸减小。根据观察到的微观结构变化,讨论了加锌对 EN AC 44100 合金机械和磨损性能的影响。
Effect of Zn Addition on the Structural, Mechanical and Tribological Properties of Al12Si (EN AC 44100) Alloy
In this study, the effects of 10 wt% Zn addition on the microstructure and properties of Al12Si EN AC 44100 alloy were investigated. For this purpose, EN AC 44100 and EN AC 44100 + 10 wt%Zn alloys were fabricated by permanent mold casting. The microstructural examinations were performed using standard metallographic techniques. The phases in microstructures were identified by energy dispersive spectroscopy and X-ray diffraction analyses. The yield strength, ultimate tensile strength, and elongation to fracture of the alloys were determined by tensile testing after measuring their Brinell hardness. The tribological properties of the alloys were examined using a ball-on-disk type wear test apparatus. It was observed that the microstructure of the EN AC 44100 alloy consists of aluminum-rich α, primary silicon and β (Al–Fe–Si) phases together with the eutectic Si particles. The addition of zinc resulted in a significant increase in the hardness and the strength of EN AC 44100 alloy but a considerable decrease in its friction coefficient and wear volume by modifying the microstructure of it. The modification caused a reduction in the size of α grains and eutectic silicon particles. Effects of zinc addition on the mechanical and wear properties of the EN AC 44100 alloy were discussed in terms of the observed microstructural changes.
期刊介绍:
The International Journal of Metalcasting is dedicated to leading the transfer of research and technology for the global metalcasting industry. The quarterly publication keeps the latest developments in metalcasting research and technology in front of the scientific leaders in our global industry throughout the year. All papers published in the the journal are approved after a rigorous peer review process. The editorial peer review board represents three international metalcasting groups: academia (metalcasting professors), science and research (personnel from national labs, research and scientific institutions), and industry (leading technical personnel from metalcasting facilities).
