“…Fine grain structures are frequently required of solidification processes to limit the formation of casting defects and improve the mechanical properties of castings [1][2][3]. Some environment-friendly physical methods, including low-temperature casting, ultrasonic vibration, and mechanical or electromagnetic stirring, have attracted increasing attention compared with chemical methods because the latter requires the addition of a refiner or modifier into the metallic melt [4][5][6].…”

An experimental study on the influence of a pulsed magnetic field (PMF) on the unidirectional solidification of pure aluminum is reported. The forced convection induced by PMF encourages a thermal homogenization of the liquid zone ahead of the solidification front. Meanwhile, synchronous solidification occurs under high magnetic intensity to form fine equiaxed grains in the entire ingot. The solidification time exhibits a trend of going from initial ascent to subsequent decent with increasing magnetic intensity. Finally, the solidification times of various temperature measurement points in the casting approach a convergence point at a magnetic intensity of 0.154 T, at which the finest grain size appears in the ingots. A thermodynamic expression with the application of PMF is discussed.

“…8 In particular, it has been found that grain refiners can increase the coherency fraction of solid and postpone dendrite coherency. 7,8,10,13 It has been recently shown that Al-5Ti-1B (wt-%) master alloy, widely used for Al alloys and commercially available, could significantly reduce the grain size of AZ91E Mg alloy. 14,15 The Al-5Ti-1B master alloys consist of Al, TiB 2 and TiAl 3 .…”

The dendrite coherency point is an important characteristic governing the castability of an alloy. In this study, the effect of Al-5Ti-1B additions on the grain size and dendrite coherency point of AZ91E magnesium alloy was investigated. It was observed that additions of 0?005 wt-%Ti led to a decrease in the grain size and the porosity level of AZ91E. This was accompanied by a significant increase in the coherency fraction of solid. However, with further additions of titanium up to 0?30 wt-%, the grain size increased and the coherency fraction of solid decreased. This was ascribed to increased growth rate, resulting from a change in the dendritic morphology from equiaxed to a lancet structure.
