Paper Title:
Effect of Composite Energy-Field on Microstructure and Properties of AZ31B Magnesium Roll-Casting Alloy Sheet
  Abstract

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.
