Abstract The morphology and crystallography of unidirectionally solidified Zn-Al eutectic has been studied by optical and electron metallography and Laue back-reflection X-ray analysis. A preferred orientation relationship between the Zn-rich and Al-rich phases has been determined from analysis of Kikuchi line patterns obtained simultaneously from both phases and found to be: (0001)Zn // (111)Al // habit plane, <1210>Zn // <110>Al ≃ // growth direction. Eutectic grains were found to rotate at rates of up to 4° per mm and both left and right hand rotations were observed. The interface plane in both left handed and right handed rotating lamellar grains lies on <5140> zones and does not contain the growth direction which is very close to <1210>. Current ideas of rotation mechanisms are reviewed, no theory being found satisfactory. The precipitation of Zn in the Al-rich lamellae due to the monotectoid reaction has also been investigated by electron metallography.
