Abstract
In this paper, in-situ temperature measurement was carried out in Low-Frequency Electromagnetic Casting (LFEC) processing for AZ80-1Y alloy to investigate the heat transfer behavior during solidification. The effects of the electromagnetic conditions (frequency and the intensity), casting velocity, cooling water flow, together with the casting temperature on the sump and the mushy zone were investigated in detail.
The microstructure observation indicates that LFEC processing could improve the metallurgical quality of magnesium billet including refining grain size, reducing regional microstructural difference and abating macrosegregation etc.. All the casting conditions affect the temperature field of billet markedly during solidification. Electromagnetic field decreases the sump depth and the difference of regional temperature field along the solidification direction.
