Effect of Composite Energy-field on Microstructure and Properties of AZ31B Magnesium Roll-casting Alloy Sheet

摘要：

With composite energy-field of ultrasonic field and electromagnetic field introduced into the roll-casting process, AZ31B magnesium alloy has been acquired successfully, during this process, the effect of composite field on structure and properties of AZ31B magnesium roll-casting alloy are studied. The result shows that the composite field can decrease the grain size greatly from 60-80μm to 12-18μm compared with the conventional roll-casting (without out-field), improving the tensile strength and yield strength by 13％ and 35％ respectively and the elongation increased by 82.2％ (average value) .Meanwhile, the microstructure of magnesium alloy obtained with the composite field are more uniform after annealing, mechanical properties are improved greatly as well.
