研究了液相线铸造 A35 6铝合金在不同保温温度、不同保温时间下的组织形成规律。电子显微镜及图象分析仪分析表明 ,由于过冷和扩散的共同影响 ,A35 6铝合金液相线铸造最佳保温温度 6 0 5℃ ;在 6 0 min时间内 ,晶核数目随保温时间的延长而增加 ,且分布愈加均匀
The microstructure of A35 6 aluminum alloy cast by liquid phase casting at different holding temperature and holding time was studied. Electron microscopy and image analyzer analysis showed that due to the combined effect of subcooling and diffusion, the best holding temperature of A35 6 aluminum alloy liquidus casting was 650 ℃. The number of nuclei varied with the holding time Extend and increase, and more evenly distributed
