Abstract EN
The three-dimensional morphology of the eutectic Ge phase in samples modified by Ca and Y in the hypoeutectic Al-20Ge alloy has been investigated by focused ion beam tomography.
Addition of Ca (0.2 wt.%) caused a modification of the eutectic Ge phase from a branched plate-like morphology to a compressed cylinder-like shape of smaller dimensions.
Addition of Y (0.2 wt.%) resulted in a transformation of the eutectic Ge phase with two types of morphology.
One type is vermicular-like in 2D and refined plate-like in 3D, while the other appears as a holey Ge matrix with an embedded eutectic Al phase of rod-like morphology.
The morphology of the modified eutectic Ge has been discussed in terms of possible growth mechanisms compared with that of the as-cast non-modified Al- 20Ge alloy and that of well-known Sr-modified eutectic Si in Al-Si system.
