	1	Microstructure Evolution of Cu-6%Ag Alloys by Modified Unidirectional Solidification Under a Horizontal Static Magnetic Field显示文摘The microstructure evolution of Cu dendrites in Cu-6%Ag alloys by modified unidirectional solidification under a static magnetic field has been investigated experimentally and quantitatively.The results show that the proeutectic Cu dendrites are finer when they are closer to the water-cooling copper mould and the unidirectional effect is more obvious,which is attributed to the higher solidification velocity.The quantitative analysis of the microstructure indicates that with increasing external magnetic flux density,the primary arms of the proeutectic Cu dendrites are refined and along a given direction.The analysis indicates that it is both the thermoelectromagnetic convection effect by the external magnetic field and the branch effect of the dendrites.

	2	Effect of Longitudinal Magnetic Field on Microstructures of Directionally Solidified Ni-Based Superalloy显示文摘The effect of a longitudinal static magnetic field on the microstructures of the superalloy DZ417G during directional solidification at the low withdrawal velocity was investigated experimentally.The experimental results showed that the application of a high static magnetic field significantly changed the interface shapes and microstructures of the superalloy.In practice,when the magnetic filed is applied,the well-ordered columnar dendrite structures still existed in the entire sample as the increase of magnetic field from 0 to 0.3 T.With the increase of magnetic field,the columnar to equiaxed transition(CET)occurred and reaches a maximum under a 0.5 T magnetic filed,and then decrease with the magnetic filed still increase.When the magnetic field is higher than 1.2 T,equiaxed grains zone on the edge of sample increased again and gradually extended from the edge to the center of the sample.Moreover,the macrosegregation may occur along with the appearance of the equiaxed grains.These phenomena should be contributed to interaction of the EMD and TEMC in liquid phase and TEMF in solid phase.
