中文摘要：在电磁超声外能场下获得1235工业纯铝板坯, 并对其进行500 ℃× 2 h(保温后炉冷到室温出炉) 高温退火处理。研究了微观组织、力学性能并对其进行了断口扫描，并和添加Al-Ti-B添加剂的1235工业纯铝板坯经过同样退火过程的组织性能进行比较。结果显示：高温退火后电磁超声1235工业纯铝板坯比添加Al-Ti-B添加剂的板坯高温退火后的晶粒要小且均匀，伸长率更高。
英文摘要：1235 prue Al plate was prepared under electromagnetic ultrasonic continuous casting, and was annealed at 500 ℃ for 2 h and with the furnace cooling to the room temperature. The microstructure, mechanical properties and scanning fracture were studied and compared with 1235 plate which was added with Al-Ti-B additives. The results show that the electromagnetic ultrasonic 1235 plate has small and uniform grain and higher elongation compared with 1235 plate added with Al-Ti-B.
