Experimental Investigation of Microsegregation in Low Frequency Electromagnetic Casting Al-4. 5％Cu Binary Alloy

摘要：

Al - 4.5％ Cu ingots were prepared by a process of low frequency electromagnetic casting (LFEC) and conventional direct chill (DC) casting, respectively. The effects of low frequency electromagnetic field on the microsegregation were investigated from eutectic analysis and electro probe microanalysis (EPMA). It was found that the amount of the eutectic, which was composed of a-Al (aluminum phase) and a phase (Al 2Cu) , as well as the dimension of the eutectic was decreased markedly. In contrast, the solute content in the a-Al phase was increased to a certAln extent with the presence of the low frequency electromagnetic field.
