摘要 In order to study the self tempering effect on the solidification of Al-Si alloy, a setup was designed to conduct experiments. The characters of β phases in different thicknesses of Al-Si samples were investigated. The results show that the size distributions of β phases obey the logarithmic normal distribution. The Brinell hardness tests were also carried out. The tested hardness results show that the hardness distribution of the casting cooled in water is evener than that cooled in air, and its averaged value is higher than that cooled in air. 为了揭示冷却速度对铝硅合金中β相的大小及分布的影响,研究其凝固过程中的自退火效应,设计了一套实验装置并进行实验。对铝硅合金试样的不同壁厚部位中的β相特征进行研究。研究发现,其颗粒的尺寸分布符合对数正态分布。为了研究不同壁厚处以及不同冷却条件下的性能,还进行了布氏硬度实验。实验表明,试样在水中冷却时其硬度比在空气中冷却时更均匀,并且其平均硬度更高。
