Abstract

This research investigates the microstructural, mechanical, and tribological properties of Al-Cu-Ni alloys in the as-cast, solutionized, artificially aged condition. In addition, the influence of cold-rolling followed by solutionizing/strain softening on the microstructure and microhardness was evaluated through a comprehensive analysis. Microstructural examination reveals that the addition of nickel to Al-Cu-Ni leads to refined dendritic structures and intermetallic phase formation. Texture analysis and microhardness measurements demonstrate the impact of mechanical and heat treatments on grain size, orientation, and material hardness. Tribological characterization reveals superior wear resistance in the heat treated Al-Cu-Ni alloy, attributed to intermetallic phases and refined microstructures.
铸造、热处理和应变软化条件下铝铜镍合金的微观结构、机械和摩擦学特性研究
本研究调查了铝-铜-镍合金在铸造、固溶和人工老化状态下的微观结构、机械和摩擦学特性。此外,还通过综合分析评估了冷轧后固溶/应变软化对微观结构和显微硬度的影响。微观结构检查显示,在铝-铜-镍中添加镍会导致细化的树枝状结构和金属间相的形成。纹理分析和显微硬度测量表明了机械和热处理对晶粒大小、取向和材料硬度的影响。摩擦学特性分析表明,热处理后的铝铜镍合金具有优异的耐磨性,这归功于金属间相和细化的微观结构。
