The Microstructure and Properties of ZL116 Alloy Obtained by the Nearby-Liquidus Electromagnetic Casting
Studying the microstructures of ZL116 alloy slurry prepared by nearby liquidus electromagnetic casting (NLEMC), electromagnetic casting (EMC), and nearby liquidus casting (NLC) by means of electron microscope and image analysis apparatus. At the same time, determining the their hardness by using hardness instrument. The results show that the NLEMC can obtain the fine and uniform equiaxed grains structure, its average-area-circle grain diameter is 28.5μm, and its rheoforming parts, hardness is 129Hv. All of these also show that the slurry microstructure and rheoforming properties of ZL116 prepared by NLEMC are the best in the three kinds of ways. At the same time, discussing the mechanism of NLEMC structure fine.
