ABSTRACT:
A method for the preparation of aligned eutectics as thin films is provided. The components of the eutectic are deposited in overlying planar layers on a suitable substrate to form a preform and a molten zone, having predetermined characteristics, is established and caused to traverse the preform melting and intermixing the deposited layers leaving the solidified thin film eutectic in its path.
