Abstract

Abstract In this study, Sr inoculated A356 alloy casted by sand-casting technique. Production parameters such as Sr concentration (wt.%), aging temperature (°C), aging time (h), and constant cooling rate were used. The effect of heat treatment on the microstructure and mechanical features of inoculated A356 materials was examined by using scanning electron microscopy, optical microscopy, and the Taguchi-based gray relational analysis method. The optimum production parameters for A356 alloy were determined as 0.03 Sr concentration, aging 300 °C temperature, and 3 h aging time. Multiple response optimization based on the interaction of these parameters provided a 30.15 % improvement in performance. Gray relational grade (GRG) experimental results showed that the most important parameter was Sr concentration, with a contribution of 76.51 %, according to the analysis by ANOVA statistical method.

基于田口灰色关系分析的 Sr 接种 A356 合金力学性能分析

摘要本研究采用砂型铸造技术铸造含 Sr 的 A356 合金。生产参数包括锶浓度（重量百分比）、时效温度（摄氏度）、时效时间（小时）和恒定冷却速率。采用扫描电子显微镜、光学显微镜和基于田口的灰色关系分析法研究了热处理对接种 A356 材料的微观结构和机械特征的影响。A356 合金的最佳生产参数被确定为 0.03 Sr 浓度、300 °C 时效温度和 3 小时时效时间。基于这些参数相互作用的多重响应优化使性能提高了 30.15%。灰色关系等级（GRG）实验结果表明，最重要的参数是硒浓度，其贡献率为 76.51%。
