Fig. 9

Directional solidification of an NPG-30wt.%DC alloy in microgravity (TA apparatus). The pulling velocity was increased from 14 µms−1 (a) to 32 µms−1 (b). Vertical dimension of the images: 5.1 mm. In this figure, the images are presented with the solidification axis z (that is, the axis of the temperature gradient) horizontal (the liquid is on the right, the solid on the left).
