| 中文摘要 | 研究了B含量及保温时间对Al 7Si合金凝固组织和冷却曲线的影响。利用热分析技术测量了冷却曲线共晶凝固段的特征值,利用图像分析技术测量了共晶Si相平均面积、形状指数。结果显示B的加入对Si相形状指数和冷却曲线特征值的影响不大;在一定的晶粒尺寸范围内共晶Si相平均面积随着初晶晶粒尺寸的减小而减小。; The effects of B content and holding time on solidification microstructure and cooling curves of Al-7Si alloy were investigated.The characteristic values of eutectic solidification section in cooling curves were measured by thermal analysis,and the average area and shape factors of eutectic phase were observed by the image analysis.It was found that B addition has a slight effect on the shape factors of the Si phase and characteristic values in cooling curve.The average area of the Si phase is decreased with the decrease of the primary grain size in a given grain size range. |
